For some reason, ideas in Hollywood come in pairs. Two asteroid movies. Two volcano movies. Two "backstage at SNL" shows. Here's another interesting two-fer I spotted when reading the latest casting reports. Both Fox and NBC have comedies in the works that will feature wheelchair-bound leads. Playing Chicken, Fox's pilot, will star Broadway baby Norbert Leo Butz as a "loudmouthed conservative" who is forced to move in with his lefty brother after an accident leaves him disabled. NBC's comedy I'm With Stupid focuses on two guys living in an assisted living facility. Christopher Thornton (pictured), who co-stars with Kevin Daniels in I'm With Stupid, was paralyzed from the waist down after a rock-climbing accident in 1992.
