The Natural Born Killers and Cheers star, who is currently appearing in the West End, has been joining in Sunday games with the group of friends for the last four weeks.

He has scored a couple of goals, calls it "soccer" and gives other goal-scorers "high fives" - even if they are on the opposing team, according to those who play with him.

He runs around, he's very energetic, just a nice guy

Michael Duncan Team-mate

The team recruited him after one member spotted him walking across the park with football boots on, and asked him if he wanted to join in.

He replied: "Sure, that would be real good," and has been turning up every week for the last month.

"I was with my friend at the time and he just walked across the pitch," Michael Duncan told BBC Radio Five Live.

"I just shouted at him and he responded to 'Woody', so we figured it was him, and he's been playing with us since."

Performance

Mr Duncan said the star was "really down to earth", but did not join the rest of the players in the pub afterwards because he had to go to rehearsals.

He is starring with Sex and the City actor Kyle MacLachlan in On An Average Day at London's Comedy Theatre.

"The standard of football in general on display in the park is not of a particularly high standard anyway," Mr Duncan said. "He runs around, he's very energetic, just a nice guy.
