Jim Carrey's Awards Show Appearance Has People Overanalyzing His Looks

Jim Carrey wowed the crowd Thursday night as he delivered a speech in French when he was honored at the César Awards in Paris ... but the iconic actor also set social media abuzz with his look.

The performer -- known for being able to contort his face more drastically than most -- had a lot of people talking.

Some online trolls appeared to think Jim looked a lot different ... while others quipped he looked like a clone.

As for the serious business ... JC was introduced on stage by Michel Gondry -- who directed him in “Eternal Sunshine of the Spotless Mind” -- a film many consider to be the actor's best dramatic work.

Another surprising moment came when Jim shouted out his girlfriend -- a rare glimpse into his private life ... the actor saying, "Thank you to my sublime companion, Min Ah. I love you."
