Carl Seiler and Madelyn (née Hughes) Seiler gave birth to Mark Edwin Seiler on May 2, 1948, in Glen Cove, New York. He was brought up in Sands Point, Long Island, where he went to Buckley Day School, Choate Rosemary Lobby, and Paul D. Schreiber Secondary School, prior to moving on from Tulane College with a BS in Financial matters.
In the wake of graduating, Seiler regarded himself as in Hollywood and went to work for RKO Pictures, a restoration of the celebrated Hollywood studio brand and the film and video auxiliary of RKO General Inc., which itself was a unit of Gencorp Inc.
Having invested some energy as leader of RKO Film Gathering, a 37-year-old Seiler was named RKO Pictures president in July 1985, supplanting C. Robert Manby. Seiler persuaded Jerry Offsay, an attorney, to leave his position as a partner at Loeb & Loeb in Los Angeles to join RKO and take over the film group. On faith, he gave me the chance to switch from law to creativity. I want to believe that he generally knew how thankful I was for changing my life [by] taking me to RKO," Offsay said in a proclamation. Offsay would later become leader of programming for Kickoff Organizations and presently runs his own organization, Parkchester Pictures.
Seiler was notable for his ability spotting capacities, both inventive and leader ability. After observing the young actor's work in theater, Seiler, then a young RKO executive, played a significant role in the casting of Denzel Washington for the George Segal dramedy Carbon Copy. The 1981 film would turn into Washington's element debut. In one more prominent model, Seiler, alongside Offsay, by and by picked the youthful Wear Cheadle, Dylan McDermott, Courtney B. Vance and Steven Weber for the cast of Cheeseburger Slope.
Seiler recognized Offsay's abilities and Marc Platt's potential early on. Platt would proceed to create the movies Legitimately Blonde, Young lady on a Train, Extension of Spies, Fantasy world and Grounds Man and a large group of stunningly effective dramatic creations including the Devilish melodic. " He was such an effect on me in my initial days in Hollywood — he saw things in me that I don't know whether I found in myself. He directed me with his insight and imparted a trust in me and a solid identity. I will be for the rest of time thankful to him for his mentorship and fellowship during those early years," expressed Platt in a proclamation.
Seiler became CEO of Capella Films in the early 1990s after working for RKO for the majority of the 1980s. The German-upheld film funding organization had a run of progress backing comedies during the ten years Seiler was in charge including Pro Ventura: Pet Investigator (1994), Idiotic and More moronic (1994), Four Weddings and a Burial service (1994), The Cover (1994) and Austin Powers: Worldwide Man of Secret (1997). However, the company was also involved in more critically acclaimed dramas, such as Alec Baldwin's The Shadow (1994) and Paul Newman's Nobody's Fool.
Seiler shifted his focus from film financing and production toward anti-piracy technology toward the end of the 1990s. He established a partnership known as Geocodex that focused on geo-encryption, initially in the film industry but later in other fields.
Seiler is made due by his life partner, the entertainer Morgan Fairchild, his sisters Carolyn Seiler Hehir and Amy Seiler and his sibling Scott Seiler.
