The best picture Oscar winner grossed $133.1m as an R rated film at the North American box office and will open on 1,000 screens on Apr 1 only in the more family-friendly version.

The move follows a much publicised campaign against the MPAA’s original rating. The R was awarded because of a scene in which Colin Firth’s character swears repeatedly as part of speech therapy.

It is understood the Weinsteins have edited that sequence to reduce the number of expletives.

“We are thankful to the MPAA for their wisdom and swift action in approving the release of The King’s Speech PG-13 release,” TWC’s president of theatrical distribution and home entertainment Eric Lomis said. “The action enables those to whom it speaks most directly – young people who are troubled by stuttering, bullying and similar trials – to see it.”
