Flagship UK production company Working Title is understood to be making up to six redundancies from its 45-strong workforce.

The company is thought to be cutting jobs as a result of the difficult economic climate, and it comes in the wake of the less robust than expected UK box-office performance of Richard Curtis’ The Boat That Rocked.

The film made around $9.1 million in the UK. Last month, Focus confirmed that it will be releasing a shortened version of the film in the US in November.

There was no official comment about the job losses but a source close to the company has dismissed rumours that there are going to a major restructure at Working Title.

It is also understood that the job losses are not related to cut-backs at Working Title’s parent company, NBC Universal.

Working Title, founded in 1984, has made more than 90 films that have grossed over $4.5 billion worldwide.

The company has a number of projects in the pipeline. Earlier this week, the company announced that it is moving ahead with a feature film version of John Le Carre’s Tinker, Tailor, Solider, Spy, which will be directed by Tomas Alfredson.) Its forthcoming releases are The Soloist; Hippie Hippie Shake, The Green Zone and A Serious Man.

Last month, Working Title’s co-founder Tim Bevan was confirmed as the new Chairman of the UK Film Council.
