Helena Bonham Carter and Imelda Staunton appeared in the Harry Potter film franchise, with Toby Stephens' mother, Dame Maggie Smith.

In the mid 1950s, Director Joseph L. Mankiewicz tried to set up a version with Audrey Hepburn and Danny Kaye, but it failed to materialize.

In Twelfth Night, the character of Orsino is several years older than Viola. However, at the time of this movie's release, Imogen Stubbs (Viola) was thirty-five; eight years older than Toby Stephens (Orsino), who was twenty-seven.

The cast includes one Oscar winner: Sir Ben Kingsley; and four Oscar nominees: Sir Nigel Hawthorne, Helena Bonham Carter, Imelda Staunton and Richard E. Grant.

Sir Ben Kingsley and Sir Nigel Hawthorne appeared in Gandhi (1982), Turtle Diary (1985), and Freddie as F.R.O.7. (1992).
