Jimmy Fallon

It's been a big week in the world of 'The Avengers'. There was the official trailer, the extended trailer, our set visit report, a bootleg clip and even the trailer for the third 'Avengers' movie, 'Avengers: Infinity War'. But, even with all those things, nothing can top the 'Avengers 2' trailer as voiced by Pee-wee Herman.

Attention, animal lovers! We've got a brand-new ambassador of adorableness for you to honor. Kristen Stewart hit 'The Tonight Show' to talk about her latest film, the drama 'Camp X-Ray,' and host Jimmy Fallon couldn't pass up the chance to ask her about the latest addition to her family. Turns out, Stewart is a big animal fan, and she's recently expanded her dog brood to include a new -- and very lucky -- little pup.

Jennifer Garner is extremely good at Catchphrase. The 'Men, Women & Children' actress hit 'The Tonight Show' last night to chat about a variety of things -- from her new film to, oops, that one time her entire family got head lice -- but she really hit her stride when it was time to play Catchphrase with host Jimmy Fallon.

"Tyler is a well-known remote control enthusiast." Did you know that about Tyler Perry? You didn't? Well, Jimmy Fallon sure did, but that didn't stop the 'Tonight Show' host from attempting -- again! -- to best the Hollywood multi-hyphenate in yet another remote-controlled challenge.

Rising star Miles Teller has already gotten a lot of attention for his next role: starring in the jazzy thriller 'Whiplash' as a young drummer (of the jazz variety) who finds himself pushed to the breaking point by a somewhat crazy (and definitely offensive) teacher, played by J.K. Simmons. The film is pretty heavy on the music, and within minutes, it's obvious that Teller couldn't have faked the musical side of his performance. Like, at all.

Dear Hugh Jackman, you know that 'The Tonight Show' is on television, right? More specifically, it's on live television in front of a studio audience, which means hundreds of people are watching the show in person, with millions more watching at home. In short, it's a very bad place to decide to cheat at a game, particularly if that game involves standing on an oversized pool table in front of said audience.

Beloved teen angst fest (and starting point for such big time talents as Claire Danes and Jared Leto) 'My So-Called Life' might have been cut short -- like, way short, the series was cancelled after only 19 episodes -- but that hasn't stopped it from enduring as a modern classic that kids still relate to (and, hey, adults do, too). The series turned twenty years old just a few weeks ago, and star Danes didn't let the day go by on unmarked. Well, sort of.

Jimmy Fallon has never been a teenage girl. Taylor Swift, however, has. Still, the veracity that Fallon brings to his performance as a teen in his fake-talk-show-within-a-talk-show, 'Ew!,' is pretty striking -- he somehow seems like more of a teenage girl than his guest, who was a teenage girl mere years ago. It's madness!

Jimmy Fallon has finally gone too far. 'The Tonight Show' host famously likes to have fun with his celebrity guests, engaging them in modified parlor and drinking games, but he's seriously gone off the deep end this time around. Fallon hosted America's sweetheart Julia Roberts on last night's show, during which he had the beloved actress join him for a brand-new game: Face Balls.

The '50 Shades of Grey' trailer is alternately steamy and scary, but late-night host Jimmy Fallon wasn't content to show it to his house band, the one and only Roots, as is. Nope, that thing needed to be modified just a touch, to really make sure that the band was paying the proper attention to their trailer-watching assignment. So the 'Tonight Show' host did what anyone would do -- he inserted a scary scream face into the middle of the trailer. Obvious, right?

James Franco has never been one to shy away from selfies, even the kind he probably shouldn't be taking and putting on the internet. Over the years, he's developed a well-oiled system for making them work, especially the ones he takes with his eager fanbase.

Don't let Kate Hudson's giggling and big smiles fool you. This is a great, great Box of Lies competitor who sits before you. On last night's 'Tonight Show,' Hudson and host Jimmy Fallon faced off for another round of Box of Lies, a game that basically hinges on a guest's ability to lie effectively.
