Continuity mistake: When Lizzie was at the Trevi Fountain, she didn't have a bag, but in the next scene at the gelato shop, she had a black bag.
Suggested correction: I looked and looked but I did not see that particular mistake.
Suggested correction: Unless you have a different cut, when they're at the fountain, you don't see below her waist and it's possible she's holding her bag at her side in her left hand. She's seen holding the black bag to her side when walking to the shop, but you also see below her waist.
