Actress Corinne Foxx says shooting underwater for "47 Meters Down Uncaged" was very uncomfortable.
"We were uncomfortable (being underwater in scuba gear). You are in your own world in that little mask. You can't communicate, or get notes, so you have to talk yourself up. In between takes, you are just sitting there in your head," Foxx said.
