Una pareja perfecta... por computadora

The role of Sheila Shea was originally written for Sandy Dennis. Co-star Paul Dooley was seriously allergic to cats though. When cat-lover Dennis would come to the script readings with up to five cats at a time, he was briefly hospitalized. The role was then offered to Shelley Duvall, who had worked with director Robert Altman on six pictures, but she turned it down. As a result, Allan F. Nicholls then re-wrote the role of Sheila Shea from an earth mother type to the young singer-groupie played by Marta Heflin. Both stars had appeared in the director's previous film Un día de boda (1978) which had premiered the previous year in 1978. Duvall and Altman would collaborate on a motion picture one more time the following year with Popeye (1980).
