What's going on with Jim Carrey?

That appearance in france the other day is so weird. Is it actually possible it's an impersonator? It sure seems like an impersonator.

Is he putting on some sort of act to prove a point?

I have seen theories as wild as they killed him and replaced him with a lookalike for the nasty things he's said about hollywood/the elite/illuminati lol.

When he claimed he is a whistleblower and why some say they killed him: https://youtu.be/eG9i7d8yfKQ

An appearance from 3 months ago, the last time some say we saw "the real Jim Carrey" : https://youtu.be/puZLQwvYABQ
