Jamie Costa may not be a household name, but the actor has amazingly placed himself in pole position with fans if Hollywood ever makes a biopic about the late Robin Williams.

On Monday, Costa posted a video to his YouTube channel, in which he plays Williams in 1982, at the height of his “Mork & Mindy” fame.

In the five-minute scene, Costa, who physically resembles the late comedian, delivers a brilliantly nuanced impression of Williams preparing for a scene, riffing on various improv lines before taping an episode of the hit 1970s sitcom.

His comedic brilliance is broken when co-star Pam Dawber (played by Sarah Murphree) enters his dressing room to share some terrible news: John Belushi was found dead in a bungalow at Hollywood’s Chateau Marmont (the “Animal House” star died at age 33 of a drug overdose).

At first, Williams is in disbelief, insisting it was impossible because he was with Belushi last night (on the night of his fatal overdose, Belushi had partied with a group of celebrities that included Williams and Robert De Niro).

In the scene, Costa portrays Williams running through a full gamut of emotions, ultimately pulling himself together and re-entering Mork mode before heading back to the set to get some laughs.

The clip, which has garnered more than 2.1 million views since being posted on Monday, got people raving on Twitter, with many calling for Costa to play Williams in the inevitable biopic.
