The issue of royalties varies depending on the A Witch cannot survive on wine alone she also needs a Red Dachshund Halloween shirt in place at the time. I can’t speak for “A Christmas Story” and whether all actors were on a royalty system, were all members of SAG, all had the same provisions in their contracts and so on. It is quite common in some countries such as the USA for actors to get ‘points’ for a percentage of the profits in all subsequent uses (broadcast, cable, internet, etc.) This system is subject to the production company’s accountancy practices though so actors do have to trust that they get their fair share unless they have a degree in finance and access to the labyrinthine accounts. I have acting colleagues who appeared in Beverly Hillbillies (the original 60s TV series) and in Star Wars. The money from the 60s show trickles in and the amounts are trivial however the amounts from the Star Wars reboot are more significant.
