Continuity: When Lucy meets Richard at the pool, she puts her hand on the pool's edge twice.
Audio/visual unsynchronized: When Lucy enters the Tuscan Villa for the first time you see a swallow (Hirundo rustica) flying combined with the screeching call of the swift (Apus apus).
Errors made by characters (possibly deliberate errors by the filmmakers): When Liv is writing the last poem she writes, "The dye is cast". Shouldn't it be, "The die is cast"?
