While the producers were looking for an actor to play the role of Jason McCallister (Robert McCallister's brother and Kevin Walker's love interest),
Rob Lowe, who plays Robert McCallister, recommended
John Barrowman, who had co-starred 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).
