FIFTY Shades of Grey writer EL James has been branded 'Fifty Shades of Crazy' by a Scots theatre producer after the threatened legal action against his new comedy play.

Robert C. Kelly is set to stage Fifty Shades of Maggie, described as 'a hysterical send-up' of EL James' story of college graduate Anastasia's S&M affair with business magnate, Christian Grey.

The storyline switches to Glasgow, where Maggie, a young lady meets the man of her dreams in the Job Centre office at her Back-to-Work interview.

But rather than being erotic, Fifty Shades of Maggie, starring Gary: Tank Commander's Leah MacRae, pokes fun at the S&M fantasy world.

And it laughs at the very notion of padlocks and chains claiming: "Any right-minded Glasga burd that's intae being dominated by a bloke needs locking up."

However, lawyers for EL James, who has sold more than 70 million books worldwide, say Fifty Shades of Maggie is just not on.

EL James' legal team said: "Our clients consider the name of the play to infringe its trademark rights. This infringement is not acceptable to our clients and in the circumstances we would therefore ask that the producers change the name of the play so as to avoid any confusion with the works."

But Glasgow-based impresario Mr Kelly, who is also set to stage the show in Dublin –and launch a Scottish tour of the Glasgow version – is adamant the title won't change. He said: "I was astounded to receive the letter. This show is a parody of EL James' book. If she thinks we are stopping the production, she is fifty shades of crazy.

"What these lawyers are trying to do, in a metaphorical sense, is tie me up in chains and handcuff me to the bed.

"But I'm not into submission. Fifty Shades of Maggie won't lay down to anyone."

The parody show, written by Leesa Harker, enjoyed a hugely successful Belfast run in January, and Mr Kelly is determined Glasgow won't miss out on 'a cracking comedy show'.

Tickets for Fifty Shades of Maggie went on sale just days ago but it's already looking to be one the Pavilion's fastest selling shows, second only to last year's Mrs Brown adventure.
