Brule's Rules! John C. Reilly, Zach Galifinaikis, Will Ferrell Rumored for 'Tim & Eric's Billion Dollar Movie'

If you have ever found yourself with a bout of minor insomnia, staying up at night and watching Adult Swim on Cartoon Network, you might have come across an odd little sketch show called "Tim and Eric Awesome Show, Great Job!"

And chances are good that if you had never seen the show before, you were pretty confused: Tim Heidecker and Eric Wareheim put out some of the oddest (and sometimes terrifying) sketches you've ever seen.

Now, Tim and Eric are working on a movie titled "Tim and Eric's Billion Dollar Movie", and according to Collider, a slew of guest stars from the TV show are in talks to appear. "Tim and Eric" regular John C. Reilly is rumored to star, which would make sense: Reilly not only appears on the show often, but also got his own spin-off show called "Check It Out with Dr. Steve Brule."

Also in talks to appear are comedians Zach Galifinaikis and Bob Odenkirk, who have also appeared on the show before. "SNL" alums Will Ferrell and Will Forte are also in talks, and are also friends of the show. The biggest and most surprising name mentioned is Harrison Ford, who has never appeared on the show. Ford has always been a guy with a bit of a sense of humor, but it's hard to say whether Tim and Eric's particular brand will scare him off.

Of course, the fact that Tim and Eric can get anyone to do anything on their show is a testament to both their network of friends and the hilarious finished product. Past guests of the show have included Ed Begley Jr., Jeff Goldblum, Fred Willard, Dave Navarro, and countless comedians.

"Tim and Eric Awesome Show, Great Job!" isn't the first Adult Swim show to make a movie: a few years back, "Aqua Teen Hunger Force" made their own feature film. The result of stretching a normally 15-minute show into a 90-minute film was that usual frenetic pacing was lost in translation, so we'll see how Tim and Eric handle the jump to a longer format.
