The first night audience of The Play What I Wrote were delighted to see stage and screen star Ralph Fiennes as the celebrity guest for the play-within-a play that is at the heart of The Right Size's tribute to comedy double-act Morecambe and Wise.
The element of both celebrity and surprise is a marketing ploy by producer David Pugh, the man behind the frequently changing casts of long-running success Art - now at the Whitehall.
In The Play What I Wrote Pugh's publicity skills get him not just mentioned but impersonated on stage - a West End first for any producer. Perhaps he'll appear as the celebrity guest himself one evening.
