Here’s the extended trailer for The Hangover starring Ed Helms from Childrens’ Hospital , Bradley Cooper from Jack & Bobby , and Zach Galifianakis.

Here’s the trailer for the summer comedy, The Hangover, starring some familiar WB faces. The Hangover stars Childrens’ Hospital’s Ed Helms, Jack & Bobby’s Bradley Cooper, and the bearded and hilarious Zach Galifianakis.

Rob Corddry isn’t the only one who’s planning on doing a little time traveling. Ed Helms (who you can also see in Childrens’ Hospital) has just signed on to co-write and star in a new feature film to be produced by Steve Carrell.

Variety announces that Helms will play a Civil-war obsessed re-enacter who is transported back in time to the actual war and must return to the present without altering history.

I love history buffs and I love it even more when people make fun of history buffs. I’m definitely looking forward to this project!

You can’t tell by my writing, but I’m a big fan of comedy -  especially comedy narrated by Stephen Colbert. So of course I’m super excited that the best new comedy of the season is going to be making its home here at TheWB.com. (That’s where I work!) Behold the trailer for “Childrens’ Hospital.”

The man behind the Childrens’ Hospital is The Daily Show’s Rob Corddry, but it also stars Ed Helms, Megan Mullally, Stephen Colbert, and lots of other very, very funny people. I’m deeply unpopular here, so no one has told me an exact premiere date, but I overheard December.
