In Twelfth Night, the character of Orsino is several years older than Viola. However, at the time of the film's release, Imogen Stubbs (Viola) was 35; 8 years older than Toby Stephens (Orsino), who was 27.
During one of the final scenes, when Malvolio reenters, it can be seen that his left shoe is missing. However, as he is walking up the stairs, you can clearly hear both heels clicking on the steps.
Malvolio: My masters, are you mad? Have ye no wit, manners, nor honesty, but to gabble like tinkers at this time of night? Do ye make an alehouse of my lady's house? Is there no respect of place, persons, nor time in you?
