In the sword fight between Hamlet and Laertes at the end, both characters are wearing jackets of the kind only used in foil fencing, to differentiate between a hit on target and a hit off target. The line in the script is "These foils have all a length?" but the weapons they hold are actually epees - which have a different target and different rules. Laertes' jacket is not properly done up, and he should have been penalised by the referee for removing his mask without permission. And a fencing piste should be 14 metres long - the one in this film is much too short.
