After reading Luke's entry regarding Step Brothers, I wanted to mention an interview that provides some explanation as to the process by which Adam McKay and Will Ferrell wrote Step Brothers.
On July 23rd, Will Ferrell, John C. Reilly, and director/co-writer, Adam McKay, were on NPR's Fresh Air with host Terry Gross. I found the 30-minute interview to be pretty cool, and was surprised when Will Ferrell and Adam McKay said that Step Brothers was fairly script-reliant, and not as dependent on improvisation as I had imagined.
I think that it's both a fun and interesting interview. You can download the podcast version off Itunes for free by going to Podcasts>NPR>Fresh Air. The "Name" of this particular podcast is "NPR: 07-23-2008 Fresh Air"

My Take On Step Brothers:
I enjoyed Step Brothers. I enjoyed it more than any other movie Will Ferrell has had a leading role in since Anchorman: The Legend of Ron Burgundy in 2004.
That includes: Semi-Pro (8.0/10), Blades of Glory (4.5/10), Stranger Than Fiction (??), Talladega Nights: The Ballad of Ricky Bobby (5.0/10), Curious George (7.5/10), Wedding Crashers (8.0/10), Bewitched (??), Kicking & Screaming (7.0/10)
I liked him in The Producers and Melinda and Melinda, but 1) it's about the overall quality of the movie and not just his performance, and 2) he obviously wasn't a lead in either. #2 is relevant to Wedding Crahsers.
I haven't seen Bewitched or Stranger than Fiction and I really don't care to. I think they are better left disregarded, and I'm pretty sure I'll never need to see them. I know Curious George is WF as a voice-actor, but I thought I'd toss it in there anyway.
I give Step Brothers an 8.5 out of 10. It's the funniest movie of the year thus far and is one of the best WF movies... but I still favor Knocked Up and Hot Fuzz (2008's Top Comedies) to Step Brothers.
