LOS ANGELES—-With a reputation as one of the most even-tempered and diplomatic gentlemen in his industry it will come as a surprise to everyone when Vivid Entertainment head Steven Hirsch losses his cool in the fifth episode of “Deeper Throat” to be broadcast on the Showtime cable network on Saturday night, March 14 (11:30 p.m.).

“Deeper Throat” tracks the behind-the-scenes adventures and negotiations that Hirsch went through with Arrow Productions to obtain the rights to make a new movie (“Throat”) loosely based on the original adult classic and the latest episode show just how stressful those dealings were. It may help to explain why the two companies continue to battle each other in court.

People who have seen an advance screening of the fifth episode of the series say Hirsch has a complete meltdown during a confrontation with Robert Interlandi, the Arrow production chief who is supposed to be looking after the interests of his boss Ray Pistol while Vivid was shooting “Throat.”

Interlandi complained loudly in earlier episodes about director Paul Thomas’ interpretation of the original movie, going so far as to wrap PT’s car in toilet paper.

The young studio exec continued to be disruptive as the production marched along, event as Hirsch shows up unannounced on the set. Within a few minutes Hirsch explodes, screaming at Interlandi. Looking back at the incident Hirsch says “In 25 years of producing movies, I’ve never seen anything like this. He’s a V.P. Production in name only as he hasn’t produced anything and we’re trying to operate a business, not play games.”

Last week Los Angeles County Superior Court Judge David P. Yaffe rejected an argument by Pistol that Arrow would be damaged irreparably if Vivid released its version of the famous Linda Lovelace film. Arrow lawyers say they will pursue a breech-of-contract suit against Vivid.
