Rick And Morty's Justin Roiland Actually Got Drunk While Recording Drunk Rick

In a behind-the-scenes clip from Adult Swim, Roiland can be seen doing shots of tequila and drinking a beer before complaining that he sounds 'too sober'.

The recording was for season three episode 'Vindicators 3: The Return of Worldender', in which Rick sets up a deadly Saw-like scenario for a team of superheroes after going on a bender.

Rick and Morty co-creator Dan Harmon explained that he encouraged Roiland to get drunk before the take.

He told the camera: "The character of Rick is a very high-functioning alcoholic - in episode 304 we need to see him get especially drunk. So I encouraged Justin to method act."

And method act he did, knocking back several shots, despite associate producer Sydney Ryan asking Roiland not to have tequila.

She explained: "The first thing I told him was don't have tequila, so of course, he had tequila... and liquor just adds a whole new aspect to Justin."

Harmon then admitted that things got 'a little creative'.

The clip then shows Roiland knocking back his fourth shot of tequila, before declaring his, quite clearly boozy, take sounds 'too sober'.

Meanwhile Ryan insists: "No it doesn't - it sounds great."

Well, it sounds drunk - I think we can all agree on that.

Later in the clip, Ryan can be heard urging Roiland to 'try and read this one on-script' as the voice-actor ad libs his lines, questions what happens to us after we die and swears at his colleagues.

Despite frequent requests from members of the crew, including Ryan, Roiland continues knocking back the shots before going off on a tangent to the camera.

But, I mean, fair play to him, he did get the job done and the take was pretty flawless drunk 'acting'.

However, Ryan doesn't seem keen for future method acting to go on, adding: "I've been on this show since season one and this is by the far least productive and messiest record day we have ever had - so... er... thanks a lot Harmon."

And the good news is fans of the show don't have too long to wait before they can see more of Roiland's fine work in the eagerly anticipated fifth season.

Adult Swim and Channel 4 have confirmed that the fifth season will premier in June meaning both US and UK fans have just a few weeks until they can finally tune in.
