I don't think the Brothers Solomon movie will be big. Here's why:
Since when did Saturday Night Live actors get to do movies without first being successful on SNL. I'm not saying the two actors (Will Forte and Will Arnett) aren't talented, but look at history of SNL performers going to movies and it just doesn't fit.
You could argue that SNL has been on a downward slide for a while now, or maybe it's just my generation of mid 20 year old's have grown out of the pop loop. But seriously think how many recurring characters these actors had, then look at the Will's:
Will Ferrell, Dan Akroyd, Adam Sandler, Martin Short, Eddie Murphy, John Belushi, Dana Carvey, Chris Farley, Jon Lovitz (hasn't starred in a movie), Tim Meadows, Mike Myers, Kevin Nealon (hasn't even starred in a movie), David Spade and a few more I haven't mentioned. Basically, I feel these actors have earned their big screen success, and the Will's have not.
They won't be the first to go from SNL to DVD in 4 hours, remember "It's Pat" - Julia Sweeney didn't make it, she was even more deserving I felt. After that Al Franken played in "Stuart Saves His Family." ....unsuccessful. In fact just about everything with the exception of Office Space (which wasn't directly from SNL) has been box office crap. This isn't going to be much different. I say no more SNL...I still watch hoping it's good, only to be disappointed time after time.
