The legendary Robin Williams sadly passed away in 2014. While Williams’ iconic films such as ‘Mrs. Doubtfire’ and ‘Good Will Hunting’ are still being watched by the world, fans are now hoping that a biopic of the late comedian will soon come out.

On Wednesday, when a five-minute video of actor Jamie Costa acting as Williams was released, the Internet went bananas. Costa released the video himself to his YouTube, titled ROBIN Test Footage Scene, which showed him portraying Williams in the early 1980s while in his trailer running through lines for his sitcom, ‘Mork & Mindy.’

While Costa is acting as Williams, clearly in the zone of his own work, actress Sarah Murphree as Pam Dawber is trying to get the actor’s attention to break the news that his good friend John Belushi‘s died. The clip goes on to show a stunned Williams trying to process the news while Dawber tells him she can’t lose Williams the same way they lost Belushi, which was to drugs.

Social media did not hold back their astonished reactions to the now viral clip. One social media user wrote, “Who else has been hoping Jamie would play Robin in a biopic since you saw his first Robin impressions?”

“It‘s one thing to resemble a person but it’s how much he sounds like him and has his mannerisms and expressions down that‘s so freaking impressive. I hope this movie gets made. I still feel his loss,” said another.

“Brilliant immersion in character, simple yet brilliant concept, great writing,” wrote another fan.
