Yes! For instance, in one of the early scenes Hamlet is also one of the guards who first saw the ghost, so the other guard is holding up a second guard's cap and when Hamlet needs to be the guard he steps over to put on the cap. Or there's the scene where Laertes is giving Ophelia advice, and Laertes is on one side of the suitcase, and then takes off his cap and steps to the other side of the suitcase and now she's Ophelia.

This also means that Ophelia's burial scene is played with no Ophelia, just Laertes jumping into an empty grave containing the Ophelia-headband.
