The producer's Weinstein Company released the royal drama in the US with an R certificate, but is now working with director Tom Hooper to remove the swearing and attain a PG-13 or PG rating.
Weinstein has been encouraged to make the changes after seeing the film's continued box office success in the UK, where it is carrying a 12A rating.
"The British numbers are huge because the rating lets families see the movie together,” Weinstein told the Los Angeles Times. “Tom and I are trying to find a unique way to do this that keeps his vision of the movie.”
The King's Speech is expanding its theatre count in North America this weekend - up to 2,500 cinemas - and The Weinstein Company is also launching a new marketing campaign to shift the focus away from the film's critical reception.
"The message more was about the critics, but now we’re trying to get across that this classic movie is just as cool as the other movies people are seeing," commented Weinstein.
The King's Speech was yesterday nominated for 12 Academy Awards, including 'Best Picture', 'Best Director' and 'Best Actor' for Colin Firth's portrayal of King George VI.
