As notorious Depression-era bank robber (and beloved folk hero) John Dillinger in 'Public Enemies,' Johnny Depp walks softly and carries a big Tommy gun. He also loves hard, lives harder and talks a whole lot of trash to pretty much anyone who'll listen.

With 'Enemies'' guns already blazing at the box office, Moviefone has compiled the movie's most memorable quotes -- you know, just in case you want to break out the badass 1930s gangster lingo at your Fourth of July BBQ.

'Ice Age: Dawn of the Dinosaurs' hasn't fared so well in the critic's department -- registering considerably worse reviews than its two predecessors -- but something tells us your kids won't mind so much.

The opening day box office returns tell us the same. 'Ice Age 3' debuted with an estimated $14 million, a fiery start that sank the red-hot 'Transformers: Revenge of the Fallen,' which earned only $10 mil Wednesday.

Let us know what you thought of the movie.

'A Streetcar Named Desire' Oscar winner Karl Malden dies at 97, 'Ice Age 3' freezes the box office dominance of 'Transformers 2' with a $14M opening day, Jennifer Aniston and Angelina Jolie top Forbes' list of Hollywood's biggest female moneymakers, and more of today's top movie headlines.

School vacation has never seemed longer. 'Potter' heads who've been breathlessly waiting two years since the last movie from the mega-popular franchise can finally exhale -- Harry, Ron, Hermione and their classmates are back for year 6 of Hogwarts training in 'Harry Potter and the Half-Blood Prince' (opens July 15), which is shaping up to be the most romantic -- and of course, mature -- installment yet.

We visited the 500,000-square foot Leavesden Film Studios in rural London (imagine an interconnecting complex of 15 Home Depots, plus dazzling exterior sets) to see where Daniel Radcliffe, Rupert Grint and Emma Watson have spent the better part of the last decade of their lives -- and to get the scoop on their latest 'Potter' adventure. Keep reading for a sneak peek from the set of 'Half-Blood Prince.'

Johnny Depp makes the gangster life look good in 'Public Enemies,' and that adorable prehistoric squirrel Scratte finds love -- and laughs -- in 'Ice Age: Dawn of the Dinosaurs.' Read our reviews of these new flicks, and get more movie recommendations for the Fourth of July weekend.

Moviefone editors Angie Argabrite and Patricia Chui talk 'Transformers: Revenge of the Fallen' -- namely, are Megan Fox and Shia LaBeouf really dating? What's up with Megan's white dress in the movie? And with the new Oscars rules, will we see a Best Picture nomination for 'Transformers'? (We're kidding. We think.)

Plus: What's opening this weekend.

Katherine Heigl and Gerard Butler are getting 'Ugly.' Brad Pitt is hunting Nazis. Vince Vaughn is having fun with 'Couples.' Matt Damon is looking plumper than ever. And those crazy 'Potter' kids must be up to something.

Behold this week's five hottest new movie trailers and clips!

In 'Harry Potter and the Half Blood Prince,' our little heroes Harry, Ron and Hermione are growing up. Wipe that tear from your eye, this is a good thing. The characters we've known and loved since we met them as prepubescent first-year Hogwarts students are now teenagers who've seen more wizard battles than any Defense Against the Dark Arts class could have prepared them for (good thing Harry took it upon himself to teach his fellow pupils a few tricks).

Billions of fans know the 'Potter' story; we've read the books. So it's not plot surprises that draw us to the 'Harry Potter' movies, it's being able to watch these actors, particularly Daniel Radcliffe, Rupert Grint and Emma Watson, bring the story to life on screen, and an important part of this film's plot involves the growing romantic tension between Ron and Hermione.
