Source? I've never once heard of a case of this. I'll freely admit that I may be wrong, but I'd be interest to hear of cases where this has happened. There may be stress during the actual production, where the actor has to perform, but after it's completed out of his/her control, why would it cause stress?
You don't get out enough. Or read enough interviews.
wondering how a potential audience will like your work causes stress. Actors in a long-running stage production and stand-up comedians can (and do) tweak their performances every night
, depending on how previous audiences have reacted to their delivery. With a motion picture, the actor does the work, trusting only in the script, director and fellow actors - and is at the mercy of the editing room - right up until opening night. But there is no chance to tweak the performance.
Sometimes movies bomb, taking an actor's career with it.
Sometimes a entire role gets left on the cutting room floor, eg. Victor Garber's Klingon in "Star Trek" (2009). Sometimes an actors two lines of dialogue gets left out at the last minute, and not restored until TV editions or Director's editions, eg. Billy Van Zandt's bridge alien in ST:TMP; Wil Wheaton's scenes in "Nemesis". Or an onscreen credit is negotiated away by an agent who says, "Trust me, 'The Phoenix' will make you a huge star!"
, eg. Judson Scott in ST II. Sometimes an actor gets replaced in the sequel, eg. Kirstie Alley not in ST III. Or forgotten forever, eg. Katherine Blum's Vulcan girl in ST III.
Sometimes an actor gets typecast, forever limiting their range. Plenty to stress about.
