Too difficult to track for a number of reasons.
Both industries have a huge number of revenues beyond their primary markets.
Remember that films get distributed not only at the cinema, but also on television, dvd, BR, sound tracks, games, digital distribution, toys, rental markets, in planes and streaming/on demand services.
Games also have subscriptions, micro-transactions, digital distribution plus many more.
I think the answer really is, both are bloody huge.
