Texas-born actor Brett Cullen, whom you may remember as Goodwyn on ABC's Lost, Vanessa Williams' millionaire squeeze on Ugly Betty and Taylor Kitsch's alcoholic father on NBC's Friday Night Lights, continues his guest starring tour of high-profile shows with an appearance on Private Practice this fall.

Below is a photo of the actor filming scenes with Amy Brenneman on the set of Private Practice last week. Brett Cullen will appear in episode #5, which has just been completed. Private Practice premieres Wednesday!

It is not clear yet who Cullen will play on the series. Could it be the previous love interest of Brenneman's character, Violet Turner, who she broke up with only to watch him get engaged to someone else quickly?
