Daniel Radcliffe has described himself as 'the intimacy coach' on the set of new movie, The Lost City, when Channing Tatum had a nude scene alongside Sandra Bullock.

In part of the movie, Bullock is pulling leeches off the Magic Mike star's naked body, and according to Radcliffe, he was on hand to supervise.
