Movies with mismatched siblings
The late Chris Farley (right, with David Spade) gave new meaning to the term "title role" in his take on Mike Donnelly in the 1996 comedy "Black Sheep." His brother Al (played by Tim Matheson) is on the campaign trail for the governorship of Washington, and the embarrassment-prone Mike desperately wants to contribute. However, his brothers' aides view him as a liability and attempt to keep him out of the spotlight with the assistance of an aide (Spade). Of course, that only works for so long.
