Memórias de Um Amor

During a January 2021 LA Times interview with Emily Zemler, Stanley Tucci said that he was originally cast as Sam and Colin Firth as Tusker, but during their pre-filming discussions they both came to agree that they should switch the roles: "'We sat down and started talking about the script and where we'd be shooting, and then Colin said, "Stanley, I think maybe we should switch roles,"' remembers Tucci, who initially brought the film to Firth after meeting with Macqueen. 'I said, 'I've been thinking the same thing." And I don't know why. I just felt it. So we read both ways for Harry-and I could tell Harry was panicked when we told him-and it was evident.' 'It was an amazing process,' Macqueen adds. 'They brought that to me, and we decided to do an audition, which is an amazing privilege for a writer-director to have two people like Stanley and Colin sitting in a room reading both roles. I picked five or 10 scenes from the film, and they were kind of brilliant at both roles, as you can imagine. But there was just something about the quintessential Englishness that Colin brought to Sam and a kind gregarious energy that Stanley immediately brought to [the American] Tusker, which made the lighter moments in the film really sing. It just felt right all of a sudden.'"

Near the beginning as the road trip starts, Donovan's Catch the Wind comes on the radio. Stanley Tucci's character, Tusker, says to Colin Firth's character, Sam, "Don't you remember this? Where were you in the 70s?" The song was recorded, released and was in the charts in 1965. Both Stanley and Colin would only have been 4 at the time, although their characters may of course be older.
