 While the producers were looking for an actor to play the role of  Jason McCallister (Robert McCallisters brother and Kevin Walkers  love interest), Rob Lowe (I) (qv), who plays Robert McCallister,  recommended John Barrowman (qv), who had costarred with Lowe in "A  Few Good Men" on the London stage. The producers offered the role to  Barrowman, and he was interested in taking it, but was ultimately  unable to work the shooting schedule around the schedule for his own  show, _"Torchwood" (2006)_ (qv).
