Mackintosh and T.J. is a 1975 American modern day Western film starring Roy Rogers in his last feature film appearance in a film that was specifically written for him. Prior to this film his most recent feature film appearances were in the Bob Hope films "Son of Paleface" (1952) and 1959's "Alias Jesse James" (a cameo).
Roy Rogers died after 1976.
The context only tells us a movie came out starring Roy Rogers in 1975. My statement was that he died after 1976. He could have died during 1976, or even in 1975 before the movie was released. He also could still be alive. Therefore, it is neither correct nor incorrect given the context. I think it was hard because the date 1976 is close to 1975.
