I mean, there's doing a movie strictly for the paycheque, and then there's being so desperate for a paycheque that you trade your dignity for it (and if you doubt that was the cost, just watch the trailer and listen to how unenthusiastic that voiceover is).
The movie's tagline is "His life just got put on paws." On paws.
... This is just a way to distract everyone from the elaborate plot he's in the process of pulling off.
But to whom did director Barry Sonnenfeld owe a favor?
Kevin Spacey's voicework is so detached and contemptuous that I'm left to assume he took the job just to see how openly he could hate the work and still get paid for it.
