Gary Oldman, Apology, Apologizes, Jimmy Kimmel
Here are some moments you might have missed during Wednesday night's late night talk shows:

Gary Oldman, who'd gotten himself into major hot water after making some inflammatory remarks -- including defending Mel Gibson's notorious anti-Semitic rant -- in a recent Playboy interview, made a conciliatory appearance on "Jimmy Kimmel Live," where he offered a long, seemingly heartfelt apology for what he dubbed "offensive, insensitive, pernicious, and ill-informed words." Acknowledging that he let his fans down, Oldman said that as a public figure, he's supposed to be an inspiration, and instead, "I'm an A-hole," adding, "I'm 56, and I should know better." Oldman's entire mea culpa is worth watching, especially for Kimmel's reaction, in which the host makes an admittedly awkward transition into talking about the actor's new flick, "Dawn of the Planet of the Apes," and quips that the distraction caused by Oldman's controversy is "not fair to the apes."

The next "Kimmel" clip featuring Oldman is decidedly -- and perhaps intentionally -- wildly different in tone, a silly man on the street segment dubbed Stranger Wrestling. The premise is fairly self-explanatory: Oldman, with a GoPro camera strapped to his head, approaches unassuming men and women in public, chats them up, then proceeds to beat the crap out of them for no discernible reason. "What a rush!" declares a loony-looking Oldman.

Over on "Conan," Oldman's co-star, Andy Serkis, demonstrated some ape calls that he learned in preparation for reprising his role as Caesar in "Dawn of the Planet of the Apes," and discussed the difference in Caesar's vocalizations -- namely, his ability to talk -- this time around. That led host Conan O'Brien to wonder what a conversation between Caesar and one of Serkis's other iconic motion-capture characters, "The Lord of the Rings"'s and "The Hobbit"'s Gollum, might sound like. Serkis obliged, and the ensuing exchange was both impressive and hilarious. Who knew mocking Conan while channeling a fictional character could be so fun?

On "The Late Show," host David Letterman chatted with "Transformers: Age of Extinction" star Mark Wahlberg about his family's restaurant (and reality show), Wahlburgers, and the different fare available. There's not much more to their conversation, though if you're craving something hearty, be warned: there's lots of mouth-watering talk about burgers, bacon, and what Wahlberg dubs the family's "special Wahl sauce." Just what that entails is left up to viewers' imaginations.

Also on Letterman, Ben Falcone discussed his new movie "Tammy," which he directed and co-wrote with his wife, Melissa McCarthy. Falcone admitted that it was stressful taking on so much responsibility for the film (he also stars in it), and said that being in charge of so many decisions -- including which forks to use in a particular scene -- was overwhelming at times. The actor also briefly discussed the infamous airplane scene from "Bridesmaids," in which he makes out with McCarthy, and how he's hoping his kids never see it.

And finally, Gabriel Iglesias stopped by "Chelsea Lately" and revealed the methods that helped him drop from 445 to 330 pounds: yoga, lots of walking, and cutting out carbs. But the comedian lamented that his fans are making it difficult to keep up his regimen, because they keep bringing him chocolate cake after stand-up shows, based off a throwaway comment he made way back in 1998 about liking the dessert. "I should have said I love cash," Igelsias told host Chelsea Handler.
