The fantastic Mr. Downey Jr. is set to star in Guy Ritchie's (eh, he's had a couple [and so has his wife...badumdum]) upcoming Sherlock Holmes project, hoping to beat out the same theme starring Sacha Baron Cohen and Will Ferrell. Written by Etan Cohen (the missing "h" makes all the difference) and helped out by Judd Apatow, it should be goofy.
