 The bathroom scene was shot over and over again for 2 days. This  scene involved Mark Wahlberg resting his bare bottom on a cold  toilet, Garrett Hedlund in a hot shower and Tyrese Gibson in nothing  but a robe for 12 hours for each of those two days. At the end of  each day, Mark Wahlberg had to be helped off the toilet because of  the long duration on the toilet and Garrett Hedlund kept having his  skin peel and prune due to being in the hot shower.
