Best television or theatrical appearance.

Im gonna say The longest yard. It had Stone cold Steve austin and the great khali in it. i still think its a hilarious movie

Tyler Mane (WCW, tagged with Kevin Nash as the skyscrapers) as Michael Myers in Rob Zombie's Halloween 1 & 2. Was also Sabretooth in Xmen and Ajax in Troy.

Macho Man Randy Savage in Spider Man.

Jesse The Body Ventura in The Running Man.

But, Andre the Giant in The Princess Bride is far and away the best though.

Rowdy Piper on It's Always Sunny in Philadelphia was funny. Rowdy might be arguably the best actor to come from wrestling (They Live.) Though he's got like 50-100 movies no one has ever heard of.

The Longest Yard gets an honorable mention for sure, only cos of the numbers of Wrestlers involved and...to be fair anyone who convinced Stone Cold to play a character who is memorable for shitting himself and Nash for having tits is very special indeed...
