Jake Gyllenhaal at Late Night With Letterman NYC Pictures

Jake Gyllenhaal headed into Ed Sullivan Theater for an appearance on The Late Show in NYC yesterday. He looked hot in a navy suit and sunglasses while waving to fans on the street. This is just one stop on the promotional tour for Jake's latest film, End of Watch. He also attended a Hamptons screening for the flick with pals Gwyneth Paltrow and Jerry Seinfeld last week. Jake will soon go from hitting the talk show circuit, though, to taking the stage. This Friday, he'll make his off-Broadway debut in a production of Nick Payne's If There Is I Haven't Found It Yet.
