Allison Williams was "devastated" after one of her Girls storylines got scrapped

Speaking on the Las Culturistas podcast, she said: "Listen, I was devastated.

"I trained, I went to, like, double classes at SoulCycle, the SoulCycle in New York City."

Allison noted that plans changing isn't unusual "in the process of writing a season of a show".

Meanwhile, Allison recently backed former co-star Zosia Mamet's calls for a spin-off series because she is so keen to get the cast "back together".

Asked if there would be a Girls reunion, she told The Guardian newspaper: "I would love it. I know that Zosia has been pushing for a spin-off, which I would voraciously consume and try to elbow my way into.

"I kind of want us all back together.

"It was so fun and it was the beginning of my career, so I didn't have the perspective I have now on just how lucky we were, or to know how unusual a creative experience it was."

Despite her enthusiasm, Allison initially struggled with viewers thinking she was similar to her narcissistic alter ego on the show.

She said: "I really desired to put distance between us, because I thought that was the kind of acting everybody respected - like, I'm wearing a prosthetic nose and I gained 40lbs, or whatever.

"And here [our characters] were, who looked basically like we looked and sounded like we sounded, but crucially said and did things that we would never do.

"It always felt weird that, since we didn't transform ourselves in some way, people weren't buying us playing characters."
