I just read Debbie Reynolds autobiography (Debbie: My Life by Debbie Reynolds and David Patrick Columbia, pub William Morrow 1988) in which she talks about working on What's the Matter with Helen? with Shelley Winters.
Reynolds suffered a collapse on set due to the stress of working with Shelley Winters, who threw frequent tantrums. Winters once kicked her dressing room door off its hinges because she was angry with Debbie Reynolds for being thin.
Shelley Winters took Method Acting very seriously, and really inhabited her role as a psychotic murderer.
