Me neither but I'll do an ignorant take and invite someone more knowledgeable to correct me: The tech to make films without human actors is available, and Hollywood studios think that they have unlimited rights forever to the digital likenesses of the actors they have contracts with. Which is pretty fucking rich from the same corporations that think we should pay for the same film on dvd, on blu ray, on blu ray in a different region, on the apple store, on the play store, and reserve the right to revoke our access to any of these where possible.

And the ad was one of their anti piracy ads ("you wouldn't download a car"), from the time where they made the nonsense claim that every pirate download was equal to lost revenue, as they tried to erode Internet privacy and bankrupt people who didn't have enough money to defend themselves in court.
