In the segment 'Père-Lachaise,' when William (Rufus Sewell) confronts Frances (Emily Mortimer), his coat is buttoned to the neck. The camera cuts to Frances, and back to William, his coat now open. The next time William appears, his coat is buttoned-up again. William (apparently) hasn't moved at all.
In the last segment, where the grave of Jean Paul Sartre and Simone de Beauvoir is shown, the audio and subtitles both say Simon Bolivar.
This is not a goof; rather, it is showing that Carol (Margo Martindale's character) is not completely confident in French and/or history.
