Did not make herself too popular on the set of
The 3 Worlds of Gulliver (1960) when she allegedly remarked that
Alec Guinness and
Noël Coward had recently co-starred with her in
Our Man in Havana (1959).
Peter Bull, who had a supporting part in the "Gulliver" film, attributed this remark (in his autobiographical book, "I Say - Look Here!") to an actress he referred to as "Marj Smith", but it was made pretty clear that he meant Morrow--there is no "Marj Smith" in the cast list of either film, and Morrow was the only American actress in both.
