What were the issue's for the production company during the production phase?

Was it an easy shoot?
There were some challenges with the filming as they had to film some parts in the studio instead of the location because it was on a boat. Also getting people on the boat was a challenge, this meant not every scripted scene went into the final version of the film.
Was any part of the film shot on location, if so where?
External scenes around Radio Rock were shot around the Timor Challenger when she was moored close to Weymouth during the spring and early summer of 2008. However, the internal and studio scenes were all shot in London's Shepperton studios on a plywood mock up of the ship, all built on a steel framework, manouvered by a hydraulic system to re-create the rocking motion of a ship at sea.
