Eric Carlin and his supposed cousin Brian were not related in real life, but were marketed as "cousins by marriage" by Miami Studios and as brothers by at least one other site that licensed a photo set. Aside from Miami Studios, "Eric Carlin" was in least two other movies in 1999 as "Brian Cox": Avenger Entertainment's Reel Life Stories of the Homo Patrol 1 and Blade's Real World 2: The Men of South Beach. He was also in a jerkoffboys.com clip with Zach, which has an associated photo set.
