Big Jim was produced by Mattel between 1971 and 1986 and was inspired by the popular G.I. Joe/Action Man 12 inch toys. The figures were shorter in height than their G.I. Joe counterparts and some characters had a push-button action feature that controlled an arm or leg movement.
The line featured an impressive range of figures, vehicles, outfits and accessories for play themes ranging from jungle and safari exploration, espionage, space, sci-fi, sports, wild west, and more.
Big Jim also released a series of action figures based on the German writer Karl May’s wild west stories, including famous characters like Winnetou and Old Shatterhand.
For a while, due to licensing issues, Big Jim was known as Mark Strong in certain markets outside of the US.
