Gabriel Byrne has been cast as the lead in the new Mark Wahlberg produced HBO series, In Treatment. The half-hour show focuses on a therapist who can't take it anymore and ends up going to see a shrink of his own. Currently, five episodes have been ordered.

I'm excited about this show because it seems like Mark Wahlberg can do no wrong lately, but does this seem like the right move for the lead? Byrne is a great actor and has had numerous roles (including the short-lived Madigan Men), but is he going to be able to pull off the part as a jovial therapist who's losing his own marbles? I realize the show is a drama, but with it's premise, it seems like humor is going to be unavoidable. Byrne always seems so serious. We'll have to wait and see if he can pull it off.
