007 star Daniel Craig will be hoping to leave viewers shaken and stirred by performing a James Bond sketch for Comic Relief.
The actor - who is currently filming new Bond movie Spectre - will appear in a "special one-off sketch", organisers have announced.
Details of the footage, to air on Friday March 13, are being kept under wraps.
It will be broadcast for Red Nose Day, which is being marked with a live broadcast, Face The Funny, from the London Palladium.
Comic Relief bosses have also revealed snaps of Professor Stephen Hawking as a special guest on the return of Little Britain.
David Walliams reprises his role as carer Lou in the sketch while the celebrated physicist appears to play the fake wheelchair bound character Andy, made famous by Matt Lucas.
Other previously announced sketches to air on the night include Rowan Atkinson returning as Mr Bean, Dawn French in the Vicar of Dibley and highlights of Peter Kay's live Phoenix Nights show.
Highlights will also include John Bishop, Eddie Izzard, Davina McCall and Walliams on stage for a reinvention of the Monty Python Four Yorkshiremen sketch and X Factor presenter Dermot O'Leary finishing his 24-hour dance marathon live at the London Palladium .
