The actress-and-fashion designer has refused to reveal what the theatre production is called, but insists it will make people laugh.
She said: ""It's going to be a comedy. I can't say any more than that, but rehearsals will start in December and I'm very much looking forward to it."
The 43-year-old is also co-producing a film, 'Function in the Junction', about northern soul music, which stars her close friend Rhys Ifans.
Sadie insists the 'Notting Hill' actor is doing well following his recent split from Sienna Miller.
She added: "From what I've seen of him, he's actually been coping very well with the situation."
Sadie gave up acting over 10 years ago following the birth of her three children with then-husband Jude Law.
In 1997, she set up a production company, Natural Nylon, with fellow British actors - Jude, Ewan McGregor, Jonny Lee Miller and Sean Pertwee and businessman friend Damon Bryant.
Ewan and Damon left the company in 2002 and Jude resigned from his position as director in 2003 following his divorce from Sadie. The company folded a year later.
Sadie and friend Jemima French set up their fashion label FrostFrench in 1999.
