Is Isaiah Washington a terror behind-the-scenes?

I already reported that Isaiah "Dr. Burke" Washington got into it big time with Patrick "McDreamy" Dempsey on the set of Grey's Anatomy recently. But, it seems this was only another notch in his belt of causing problems behind-the-scenes of his TV shows, according to a repoort on TMZ.com. In 2000, Washington was shooting the Showtime spin-off of Soul Food. Washington and Nicole Ari Parker, who played his wife, were shooting a scene in which he was supposed to give her a casual kiss. Instead, Washington grabbed her and planted a "forceful, aggressive kiss." Nicole was angry, which then infuriated Washington who began screaming at her. At that point the director stepped in to correct him, and Washington went off on him. Executive producer Tracey Edmonds then took over and Washington went off on her. And the plot thickens even more, because I've heard that Boris Kodjoe, Nicole's husband, may be in talks to replace Washington on Grey's. In 1997 there was yet another incident on the set of the TV show High Incident. Washington was a guest star on the show, but we're told the gig ended abruptly after he had a physical altercation with a crew member, serious enough that police were called. If Washington has some issues or problems with his temper, I hope he gets the help he needs.
