Movies in which performers show skills other than acting

I have always loved to watch movies in which the performers bring a personal skill to the role. Generally it’s something musical, my favorite is watching Robert Duvall in Tender Mercies.

Margot Robbie’s figure skating in I, Tonya is another one (though she did have a double in some shots).

Number three is DB Sweeney in Eight Men Out. Of all the actors who have portrayed a major league baseball player in a film, he looked like the real deal.
