The 'Snowden' star has revealed he has signed up to the as-yet untitled project alongside his good friend, but admitted just because the script is being written, by Michael Bacall, it doesn't mean the project will definitely end up hitting the big screen.

He said: "Chan and I are working on a musical and my friend Michael Bacall is writing it, he wrote '21 Jump Street'.

"There are no guarantees in the movie business just because a script is getting written that doesn't mean a movie will be made but I think this could be really good.

"Chan and I have wanted to do a musical for years, I really hope it works out."

Channing stars as the self-titled stripper in the 'Magic Mike' movies but Joseph insists he won't be following in his 'Stop-Loss' co-star's footsteps by baring all in another film in the franchise after already seeing what it was like during a 'Saturday Night Live' sketch.

He said: "I did a Magic Mike routine on SNL, do we need an hour and a half of it? Do we need it?"

Another thing the 35-year-old actor isn't sure people need to see is mass surveillance, and he is concern it could become prominent in the US following Donald Trump's US Presidential victory.

Speaking to Tom Green on The Hits Radio breakfast show, Joseph added: "A lot of people I know didn't feel so strongly about mass surveillance until we got a new president elect.

"He is someone you can much more easily imagine taking advantage of mass surveillance tools to spy on or discredit those who oppose him all of a sudden those mass surveillance tools seem a lot scarier."
