HOW TO BE Movie Trailer with Robert Pattinson

Check out the trailer for HOW TO BE starring Robert Pattinson, Rebecca Pidgeon, Jeremy Hardy, and directed by Oliver Irving.
Not too long ago I posted some pictures of Robert Pattinson in How to Be and now we get a look at the trailer, which is not exactly what I was expecting. It looks quite bizarre, but at the same time I want to watch it.
As I previously explained, the movie comes out on April 27, and IFC Festival Direct will make it available On Demand on April 29.
Watch the trailer for How To Be below.
How To Be Synopsis: At first fancying himself an “enigmatic poet,” twentysomething Art (Robert Pattinson), gradually realizes that he must take action if he’s going to escape his depressed life as a struggling musician in London. A solution comes in the shape of a book titled “It’s Not Your Fault.” Not content to just draw inspiration from its pages, however, Art invites the elderly author of the book to come live with him and his parents, which quickly becomes a painfully funny journey about dysfunction and growing up
