Despite its stars sharing equal billing, Powell played the biggest role in the company's early success and growth.

Actress/director Ida Lupino was brought on board as the pro forma fourth star, though unlike Powell, Boyer, and Niven, she owned no stock in the company.

It hosted the pilot episodes for Trackdown starring Robert Culp (which in turn hosted a pilot for Wanted: Dead or Alive with Steve McQueen), The Westerner with Brian Keith, Black Saddle with Peter Breck and Russell Johnson and The Rifleman, starring Chuck Connors, Johnny Crawford and Paul Fix.

The schedule of who pulled leading man duty was largely determined by the actors' movie commitments, thereby giving Niven, Boyer, and Young additional work between film roles.

Four Star also helped bring some prominent names in television and movies to public attention including David Janssen, Steve McQueen, Robert Culp, Chuck Connors, Mary Tyler Moore, Linda Evans, Jeannie Carson, Lee Majors, The Smothers Brothers, Aaron Spelling, Dick Powell, David Niven, Joel McCrea, Charles Boyer, Ida Lupino, Richard Long, Peter Breck and Sam Peckinpah.

[5] An ad executive named Thomas McDermott was brought in to run the studio for Niven, Boyer, and Powell's family.

He directed the company, employing his only son, John Charnay as Director of Public Relations, as well as employing many of Hollywood's leading producers, stars, and executives of the late 20th and early 21st century, including Deke Heyward, Morey Amsterdam, Dick Colbert, Tony Thomopoulos, and collaborating with Aaron Spelling and George Spota for continued film and television projects, as well as many Hollywood stars and starlets before many producers advanced to create their own companies.

[23] By 1987, David Charnay had sold Four Star to Robert Seidenglanz's Compact Video Systems, which was then majority-owned by Ronald Perelman.

[24] After Compact Video shut down, its remaining assets, including Four Star, were folded into Perelman's MacAndrews and Forbes Incorporated.

[26][27] Four Star International is now owned by The Walt Disney Company, with most of its library of programs controlled by 20th Television as a result of the buyout between Rupert Murdoch and Ron Perelman in 1996.
