Patrick Stewart Christmas Carol: how much did it cost to make?

Our 9-year old son is fascinated by all the film/TV versions of Scrooge / A Christmas Carol that we have bought so far. He has Asperger's syndrome, so he absolutely loves making lists of things and putting them in order.

He makes many interesting comparisons between the versions (and back to the original book) but his latest quest for list-fodder is to find out how much each of the versions cost to make (either at the time or translated into today's money). We found figures for Disney/Jim Carrey ($190M) and Muppet Christmas Carol ($12M) but we are stuck for the Patrick Stewart (and others).

Does anyone know where we can find this kind of information? We would be really grateful. We also want to get the same relevant info for the Albert Finney, Alastair Sim, George C Scott and Michael Hordern TV versions too.

All advice gratefully received.

Many thanks

Geoff
