I don’t even know what to call this other than “Aziz’s brain works in odd ways” but it occurred to me that there are movies which reunite actors from totally unrelated films. For example, we know Christopher Reeve was the iconic Superman, and Michael Keaton was the original big screen Batman. So with all the talk of a Supes vs Bats movie out there, some people fantasize about a Keaton-Reeve casting. But it’s been done! The movie was called Speechless and costarred Gina Davis.
Likewise the mom and dad from Seventh Heaven (on television) were both sidekicks to Captain Kirk in Star Trek movies (mom was Gillian from IV:The Voyage Home and dad was Decker from I:The Motion Picture).
Can’t think of any other examples off the top of my head but do chime in if you’ve got one.
