Analysis of information sources in references of the Wikipedia article "Popeye the Sailor Meets Sindbad the Sailor" in English language version.
Popeye the Sailor Meets Sindbad the Sailor was the first Popeye cartoon made in Technicolor as well as the first American animated film to be billed as a feature (running over 16 minutes, it took up two reels), and it is where the Fleischer brothers' "setback process" was showcased to its full potential. [...] First used in the 1936 Popeye short For Better or Worser, the process gave off the illusion that two-dimensional characters were able to maneuver in a three-dimensional space.
