Mad Men alum Vincent Kartheiser is denying allegations of misbehavior on the set of HBO Max series Titans.
The star, who plays villain Jonathan Crane, a.k.a Scarecrow, on the new third season of the DC superhero show, was the subject of two recent internal Warner Brother Television investigations of alleged negative behavior. No other parties have been identified.
"Vincent Kartheiser vehemently denies the allegations," the actor's rep told E! News on Saturday, Aug. 14. "Warner Bros. investigated this matter and made clear to Mr. Kartheiser its expectations for behavior on the set, and he agreed to comply with their directives."
A source close to the situation told E! News that the first complaint about Kartheiser involved "sophomoric behavior of a verbal nature" that required "corrective action" but not termination. Warner Bros. Television's labor relations department investigated and interviewed relevant parties and also addressed the issues directly with the actor and counseled him on behavioral matters.
Weeks later, as production was nearing an end, Warner Bros. received a new complaint about Kartheiser, the source said. They added that after another investigation, the studio put additional measures in place, including assigning a representative to monitor activities on set. The insider noted that due to COVID protocols and quarantine in place for international travel to Canada, where Titans is filmed, U.S.-based investigators were not able to physically be on set.
Warner Bros. and HBO Max declined to commented on the allegations or the investigation when reached by E! News.
Kartheiser is best known for playing Pete Campbell on Mad Men and Connor on Angel. He joined Titans for season three, which debuted on HBO Max on Thursday, Aug. 12.
