Outside of Christopher Walken, Michael Caine is probably the most impersonated celebrity voice out there, so much so that the phenomenon has gotten back to him and he’s a bit offended.
Here he does an impression of himself, or at least an impression of what other people claim he sounds like. Apparently it’s in birthday cards and sat navigation systems. Wait, hold the phone, I can have Michael Caine giving me directions through my GPS? Excuse me, I have to go research this immediately.
