The Final Curtain.

The Final Curtain is a British film from 2002 directed by Patrick Harkins and starring Peter O'Toole. It tells the story of J. J. Curtis, ageing gameshow host played by O'Toole, who hires novelist Jonathan Stitch (Adrian Lester) to pen his biography, in the hope of sealing his immortality in the hearts and minds of the British public. This is made more difficult by his rivalry with fellow gameshow host Dave Turner (Aidan Gillen), and events from his past.
