Fox doesn't unveil its fall schedule until Thursday, but Variety reports that the network is expected to add four new dramas and three new comedies. Changes are also in store for many returning shows, including Malcolm in the Middle moving to Sundays at 9 pm/ET and The Bernie Mac Show shifting to 8 pm/ET on Wednesdays opposite ABC's My Wife and Kids. Critical fave 24, meanwhile, will return for a second 24-episode day.
