Smile was composed by Charlie Chaplin for his 1936 film Modern Times, with lyrics later added in 1954 by John Turner and Geoffrey Parsons. Many singers have recorded it, but Jimmy Durante's warm, gravelly interpretation became one of the most recognisable. Its profile rose again when this version featured in the 2019 film Joker, connecting the song's hopeful lyric to the character's painful story. Shared online as a short clip, it now travels through edits and tributes where that mix of sorrow and comfort fits perfectly.
