LONDON — FilmFour, the movie arm of the U.K.’s Channel 4, has appointed Mark Rudolph deputy chief executive.

Rudolph, who reports to chief exec Paul Webster, is an American with an extensive background in European cable and satellite television, but no film industry experience.

His role at FilmFour will lighten Webster’s managerial load by helping to develop and execute the company’s ambitious business plan, and overseeing day-to-day management.

Rudolph’s past work includes seven years at HBO; helming the European expansion of both CNN and TNT/Cartoon Network at Turner Intl.; serving as chief exec at Nethold Electronic Media, supervising the launch of digital TV services in several countries; and, since last year, working as senior VP of MIH/mindport, an interactive TV venture.

Despite all this experience, Rudolph will not be directly involved in Channel 4’s infant pay film channel, which also is dubbed FilmFour.

“Mark Rudolph is a vital addition to the FilmFour family, and gives our management team extra strength and depth,” Webster said. “His enormous experience, as well as valuable negotiating and business knowledge, will augment our exciting and successful expansion. He’s a keen lateral thinker and will bring added insight and intelligence to our strategic planning.”
