Favourite minor appearances/cameos by non-actors
As the title says, which films have instances where there was a minor appearance/cameo by someone who isn't really considered an actor, and which you genuinely enjoyed.
One of my picks, despite (or maybe because of) how absurd the role was, was Elton John, in the 2nd Kingsman film. I found myself at least smiling through most of the scenes that featured him.
Note: The person can either make an appearance as their real, celebrity selves, or they can be playing an actual character. Both are valid.
