The 53-year-old, who soared to worldwide fame playing Ross Geller in the hit sitcom, was pictured by Ian Lawrence at Grange Farms in Northbourne Road.
He remained behind the wheel of a blue campervan which was being towed along the road.
The cameras were thought to be rolling for a TV advert.
Mr Lawrence, who works at the farm, said: "I managed to grab a picture as he came by the farm workshop.
"The production crew had set up camp for the day in our yard, although you can’t see his face close, it was definitely him.
"He is at the wheel but not driving, as it is on a towing rig.
"He arrived about lunchtime and they were all clearing up by 4pm."
