According to TVLine, the 'Dawson's Creek' veteran will play Rex Tamlyn, described as an "overconfident, hard-partying playboy." The character is a partner in a Facebook-esque website that's devoted to hooking people up for fleeting romantic trysts.
Like 'The Social Network,' there's a lawsuit around the idea of the site, but with this case there are a few murders mixed in. It's 'Criminal Intent,' what do you expect? Thad and Trent Luckinbill also guest star.
Van Der Beek will appear in the ABC midseason comedy 'Apartment 23' as a fictionalized version of himself.
