Ricky GervaisRicky GervaisRicky Gervais has come a long way from Slough, and the boy done well, very well...

Now he's lined up a galaxy of star names to appear in the new series of his show Extras.

The celebrity guests were meant to be top secret until the end of the summer, but The Sun has revealed all.

And the Extras are... David Bowie, Orlando Bloom, Chris Martin, Ian McKellen and Daniel Radcliffe.

Shall we go on? Oh OK, Jonathan Ross, Richard and Judy, Moira Stewart... and the entire cast of Holby City.

Some outrageous scenes have already been filmed.

In one, Sir Ian tells Ricky's character Andy to snog him - before calling out for Vaseline.

Orlando BloomOrlando BloomDavid Bowie sings during his appearance, but Andy misses out, despite bribing his way into the VIP area of a private club to watch. He gets kicked out immediately.

And an amorous Orlando Bloom gets rejected by Extras' regular Maggie, played by Ashley Jensen.

An insider said: "Orlando demands she kiss him - but she refuses and he's incensed. It's brilliant - Orlando totally sends himself up."

Apparently, even Madonna asked for a part, but had to pull out due to her world tour.
