(written from a Production point of view)
Robert S. Sallin (born 1931) was the producer of Star Trek II: The Wrath of Khan. He was given the job of making this production with a much smaller budget than was used to make Star Trek: The Motion Picture. Among his achievements was changing the Starfleet costumes from the one-piece jumpsuits of The Motion Picture to the more comfortable uniforms seen in Star Trek II and subsequent films. He also ensured that James T. Kirk received his famous dramatic entrance.
Star Trek II is the only film Sallin has produced.
During the 1958-59 television season, Sallin served as a production assistant on NBC's adventure series Steve Canyon. He went on to direct the 1969 Warner Bros/Seven Arts drama The Picasso Summer, which was TOS guest star Theo Marcuse's last film. He later directed episodes of the CBS shows The American Girls and The Mississippi, and two episodes of the NBC series Riptide, including one with Miriam Flynn.
