Judith Proctor's Journal

Dear Lazyweb,

Google has failed me, and my fingers are too sore to search further.  (I'm using my voice dictation system this morning) I'm trying to recall a conversation by a famous actor, when another actor was boring him by a lengthy description of method acting.  When the other man asked him what he did, his put-down was something along the lines of "I act".

Does this strike any bells with anyone?  Or can anyone recall a similar quote?

added - Many thanks to all those who managed to pschically realise what it was my brain was trying to remember.  Olivier and Hoffmann in Marathon Man.
