When someone is as talented as Robin Williams, we often say they are one-of-a-kind. Even after his death, Williams continues to entertain us with videos of his comedy and many of his movies.

As it turns out, Robin Williams may also have a doppelgänger, and it comes in the form of actor Jamie Costa. He is the one who was selected to play Robin Williams in the possible upcoming film of his life.

People are amazed after the “test footage” was posted to Costa’s YouTube channel. In the appearance, you can hardly believe it isn’t Williams who is speaking because he nails the appearance and the voice so perfectly.

He even has his mannerisms down perfectly.

In the video, Costa is playing Robin Williams as he is working in his early years on the Mork and Mindy show. An actress sits in front of him, portraying Pam Dauber, as she tries her best to get his attention.

Finally, she just blurts out that John Belushi has died.

Williams, who happened to be with Belushi that night, responds with sadness and humor.
