Goofs

When Charlie comes home from work, Fido is asleep laying on his back. The camera cuts to a close-up of him and he is now laying on his left side. In the next shot, he is laying on his back again.

When Lena and Charlie look at the men behind them in her compact mirror, the reflection shown is not plausible.

When the last brother (Richard) is finally seen, the dialogue of the long shot with Édouard and Richard climbing up the snowy hill has been completely reworked in post-production, so much that most of the lines are visibly off-sync.

When Lena and Charlie walk home after work, the shadow of the camera can be seen on their coats.
