Commuters were surprised when their daily travel included a film crew taking over a train as it travelled to Norwich.

Two services from London Liverpool Street to Norwich played host to the crew and British film and TV star Martin Freeman, who was spotted as part of the production.

Jack Skevington, 23, saw the filming taking place as he boarded the train at Stowmarket on Monday (February 20).

He said: "On my commute to work I got on the train from Stowmarket to Norwich and as I was about to get on I was asked to move down as they had booked out two carriages for filming.

"There was a massive crew on board the train.

"As I got to Norwich and got off the train, they all got off as well and that is when I spotted Martin Freeman."

It is not yet known which project the film crews were working on.
