The Rocky and Rambo star Sylvester Stallone took to the football pitch at Goodison Park before watching Everton play Reading.
Stallone is a friend of Blues shareholder Robert Earl
Stallone, 60, got a rousing reception from the 30,000 plus crowd on Sunday as he held up a blue-and-white Everton scarf and punched the air on the field.
He said cheers from the 30,000-strong crowd turned him into an Everton fan.
Stallone is a friend of Blues shareholder Robert Earl and is in the UK to promote his latest film.
Rocky Balboa is his sixth film in the series.
The original Rocky, released in 1976, told the story of a small-time boxer from Philadelphia who gets a shot at the world heavyweight title.
Speaking at the match, Stallone said he thought David Beckham would be a "big hit" in the United States when he starts playing for LA Galaxy.
"That's it! We've decided to steal your entire sport," he said.
"We're bringing it west. No, actually I think it's fantastic, history repeats itself, maybe the seventies was too soon, with Pele and Beckenbauer, this could be great for everybody."
