Colin Farrell has been hanging low since rehab. He has spent time in NYC filming and walking his son in the park. Tonight he is at the premiere of "Wristcutters A Love Story" starring Shea Whigham who is in the picture below with Colin. They were co-star's in Tigerland. Colin looks much better here than during his Miami Vice filming days but he also looks like the bad boy we remembered from a few years ago.
