The actress was spotted having a ball on set alongside her co-star, Richard E. Grant.

Donning a brown wig and wearing a frumpy '80s ensemble, the star looked a world away from her red carpet self.

The movie is based on the life of literary forger Lee Israel, a celebrity biographer who counterfeited and sold letters written by A-listers.

Melissa's latest makeover comes after her she used her SNL stint to mock some of Spicer's more controversial attributes, namely his use of 'alternative facts' and contentious relationship with the press.

In her opening remarks as the Press Secretary, she says: 'Before we begin, I know the press and myself have gotten off to a rocky start.

'When I say rocky I mean in the sense of "Rocky" the movie because I came out here to punch you in the face, and also I don't talk so good.'

'Spicer' quickly grows adversarial, shouting 'I am here to apologize on be half of you to me,' referring to how he feels he has been treated in the past few weeks. McCarthy continues 'That apology is NOT accepted, cause I'm not here to be your buddy, I'm here to swallow gum and to take names'

The sketch focuses around the Press Secretary's propensity to lash out at the media, and includes jabs at CNN and Glenn Thrush of the New York Times. 

When describing a recent public event held by the President, the Spicer impersonation yells 'Everyone was smiling, everyone was happy, the men all had erections, every single one of the women was ovulating left and right, and no one, no one was sad.'

Later, in an impersonation of Spicer taking questions from the press, he quickly grows frustrated at journalists asking about the role of chief strategist and key adviser Steve Bannon, turning to props to explain the President's executive order. 

When talking about radical Islamic terrorism, holds up a stuffed moose and a stuffed lamb, and said 'He will not be deterred in his fight against radical moose-lambs.'
