Nickelodeon/20th Century Fox Joint Venture movies

In 1993, Nickelodeon signed a 2-year contract with 20th Century Fox to make feature films. The joint venture would mostly produce new material, though a Nickelodeon executive did not rule out the possibility of making films based on the Nicktoons: Doug, Rugrats and The Ren & Stimpy Show. But none of this movies were produced.

Why The Movies Were Cancelled

 * 1) Viacom, Nickelodeon's parent company acquired Paramount Pictures in 1994 and they would distribute the movies instead
 * 2) Nickelodeon/20th Century Fox joint venture contract expired in 1995
 * 3) Doug was sold to Disney in 1995, due of the show's production studio, Jumbo Pictures sale to Disney and the show moved to ABC in 1996
 * 4) The creatives differences with the creator of Ren & Stimpy, John Kricfalusi (John K.) and an inability to market that property in a family-friendly manner instead of a "cynical and gross humor" scuttled that film
