Eddie Izzard is working on a new stand-up show.

The comic, whose stock in America is on the up with his role in The Riches TV drama, is currently performing a number of work-in-progess gigs in New York.

He has been in the off-Broadway Union Square Theatre since February 12. The run was due to end on Friday, but it has now been extended to March 8.

It follows a similar series of workshop gigs in London’s intimate Arts Theatre.

Izzard’s last major tour, Sexie, was in 2003, but was generally not considered his best show. However, he had a successful run at Montreal’s Just For Laughs comedy festival last summer.

Izzard also has one date scheduled in the 2,700-seater Arlene Schnitzer Concert Hall in Portland Oregon on July 15, which may be part of an imminent tour..
