Comic-Con International: San Diego is the ultimate pilgrimage for geeks of all stripes. This is the place where hundreds of thousands of people descend to see the latest sneak peaks of upcoming movies, TV, games, and comics. Where they can bump elbows with celebrities and score all the exclusive swag they can carry.

Comic-Con is exciting, but it's also an exhausting experience for everyone involved. We're going to try to make things a little easier. Here are the biggest panels and events at this year's SDCC that are worth battling the crowds to see.

WEDNESDAY, JULY 19:

1. Warner Bros: Special Sneak Peek Screenings (6:00-10:00pm Ballroom 20)As usual, Wednesday is "Preview Night" at SDCC, and it's mostly geared towards collectors lining up to buy exclusive collectibles. But DC fans may want to make room for this event, as WB will be screening a new episode of "Teen Titans Go" and offering an early look at The CW's "Black Lightning" and Syfy's "Krypton."

THURSDAY, JULY 20:

2. Anything Goes with John Barrowman (11:00-11:50am Hilton Bayfront - Indigo Ballroom)Anyone who's ever attended a panel with "Arrow" and "Torchwood" star John Barrowman knows that he puts on a hell of a show.

We don't know if the actor will reveal anything about his potential involvement in "Arrow: Season 6" at this panel, but it is safe to expect plenty of singing, dancing, and improv as Barrowman entertains his audience. It's worth venturing outside the confines of the convention center for this one.

3. 20th Century Fox (11:30am-12:30pm Hall H)This is the first big movie panel of the convention. We're not sure what properties Fox will be focusing on, but expect new details on upcoming X-Men-related projects like "Dark Phoenix," "Deadpool 2," and "New Mutants." Also, we will see footage from the "Kingsman" sequel.

4. 'Battlestar Galactica' Reunion (2:30-3:30pm Ballroom 20)Last year's SDCC offered a long-awaited reunion for the cast of 1986's "Battlestar Galactica" reboot to get back together. If you're a fan of this series, this is basically a once-in-a-lifetime opportunity.

5. 'Batman: Mask of the Phantasm': Remastered and Ready (4:15-5:15pm Room 6A)"Batman: Mask of the Phantasm" is one of the greatest Batman movies ever made, and it's finally hitting Blu-ray this month. This panel will feature key players like Bruce Timm, Kevin Conroy, and Alan Burnett as they reminisce about the film and preview some of the remastered footage.

6. Marvel Television: 'Marvel's Inhumans' (6:15-7:15pm Ballroom 20)The MCU is expanding even further into the TV realm this fall as the Inhumans make their long-awaited debut. Executive Producer Jeph Loeb will moderate this panel as various guest stars stop by to tease what's to come in the new ABC series.

FRIDAY, JULY 21:

7. 'Young Justice' Q&A (10:00-11:00am Room 6BCF)"Young Justice" fans finally got their wish earlier this year when it was announced that the animated series will be making its return via DC's new streaming service.

Creators Greg Weisman and Brandon Vietti will be among those attending this panel, as they shed more light on what to expect from the third season and (hopefully) when it'll be making its debut.

8. 'Fear the Walking Dead'/'The Walking Dead' (11:15am-1:15pm Hall H)Once again, AMC will be taking over the coveted Hall H for a two-hour block as cast and crew members from both "Walking Dead" shows stop by to tease what to expect from upcoming storylines. The first hour will be dedicated to "Fear the Walking Dead," with the second moving to "The Walking Dead."

9. 'Game of Thrones' (1:30-2:30pm Hall H)If you can score a seat for the "Walking Dead" panel, you might as well stick around for the next panel. HBO will be shedding more light on the just-premiered seventh season of "Game of Thrones," with plenty of mystery actors showing up to tease what's coming as the show moves towards its big finale.

10. FOX's 'The Gifted' (3:45-4:45pm Ballroom 20)We're hoping to learn plenty about Fox's upcoming X-Men movies at Thursday's 20th Century Fox panel, but if you want to know more about the TV spinoff "The Gifted," you'll want to make room for this panel.

11. 'Marvel's The Defenders' (5:15-6:15pm Hall H)Marvel will follow up Thursday's Inhumans panel with another TV-centric panel, this time focused on Netflix's highly anticipated superhero team-up.

Jeph Loeb will again be in attendance, and we're hoping he'll be joined by Charlie Cox, Krysten Ritter, Mike Colter, and Finn Jones. Is it too much to hope Sigourney Weaver might pop by, also?

12. 'Batman and Harley Quinn' Premiere (Ballroom 20)DC's next direct-to-DVD animated movie also happens to be a continuation of the much-beloved "Batman: The Animated Series," one that forces Batman to join forces with Harley Quinn to defeat Poison Ivy and the Floronic Man.

And if you can't wait for the movie's August release date, you'll get a chance to see it early at DC's Friday night screening.

SATURDAY, JULY 22:

13. Warner Bros. Pictures (11:30am-1:30pm Hall H)Expect this to be one of the more in-demand panels at SDCC this year. The focus will be on upcoming movies like "Justice League." and "Blade Runner 2049," as well as next year's "Ready Player One." Hopefully we'll learn more about the next film in the "Fantastic Beasts" series as well. Look for director Steven Spielberg, actor Harrison Ford, and the entire cast of "Justice League" to headline this panel.

14. 'Star Trek: Discovery' (2:30-3:15pm Ballroom 20)CBS' highly anticipated new "Star Trek" series is getting its own panel. We don't know which cast and crew members will be in attendance, but no doubt there will be new footage to show and more details about how this series will fit into the larger Trek universe.

15. Netflix's 'Stranger Things' Season 2 (3:00-4:00pm Hall H)The second season of "Stranger Things" just got an October release date, and the series will be making its SDCC debut this year.

Expect various cast and crew to stop by to preview new footage and answer various fan questions.

16. The CW Arrowverse Panels (3:30-6:30pm Ballroom 20)If you love The CW's superhero shows and have three hours to kill, you'll probably want to sit in on this mega-block of panels. All five series -- "Supergirl," "DC's Legends of Tomorrow," "The Flash," "Arrow." and the upcoming "Black Lightning" -- will have 40-minute panels dedicated to teasing what's to come in the fall season. We will also get a look at the new villains that will be threatening the Arrowverse this time.

17. Robert Kirkman and Todd McFarlane in Conversation (3:30-4:30pm Room 6DE)As much as TV and film announcements have come to dominate SDCC in recent years, this is still a show geared towards comic book fanatics.

If you make a point of attending any comic-focused panel this year, it should probably be this one, where "Invincible"/"The Walking Dead" creator Robert Kirkman and "Spawn" creator Todd McFarlane have a one-on-one chat about the industry and reminisce about their respective careers.

18. 'Westworld' Panel and Q&A (4:15-5:15pm Hall H)Help fill the wait until "Westworld" finally returns to HBO by attending this star-studded panel that features pretty much every major cast member not named "Sir Anthony Hopkins." They'll even be answering fan questions, though we imagine that will only do so much to address the show's many lingering mysteries.

19. Marvel Studios (5:30-7:00pm Hall H)Fans who attended the D23 convention this past weekend already got a good look at upcoming MCU projects like "Avengers: Infinity War." That said, we expect Marvel's Kevin Feige will have plenty more to reveal at this panel, which promises to be one of the busiest -- and biggest -- of the show. (Expect to see all or most of the Avengers cast on stage.)

SUNDAY, JULY 23:

20. 'Marvel's Spider-Man' Animated Series World Premiere (10:15-11:15am Room 6A)Spider-Man is getting a brand new animated series to capitalize on his new movie, and SDCC will be your first opportunity to see how "Marvel's Spider-Man" stacks up to shows like "The Spectacular Spider-Man" and "Ultimate Spider-Man." Marvel will be screening the two-part series premiere at this panel.

21. Doctor Who (2:00-3:00pm Hall H)The BBC pretty much broke the Internet with the announcement that the next incarnation of Doctor Who will be a woman. Expect that announcement to be a big topic of discussion at this panel, which will also basically serve as the final bow for current star Peter Capaldi and showrunner Steven Moffat.
