When the director was asked if the Harry Potter star had a cameo in the film, he jokingly denied it saying, "Not true! He was just walking his dogs."
While the film's details are "being kept under wraps" on IMDb, both Radcliffe and Tomei appear to be part of the cast. Tilda Swinton, Brie Larson and Ezra Miller are also listed.
