Answer
The Double Man is not a film that Britt Ekland appeared in. Ekland is a Swedish actress known for her roles in films such as The Night They Raided Minsky's (1968), Get Carter (1971), and The Wicker Man (1973). The Double Man, on the other hand, is a 1967 spy thriller starring Yul Brynner and Britt's future husband, Peter Sellers.
