Some actors come to Mr. Foxes office, generally to help
get into characters or to help with .. other issues, such as addictions.

Called away to the phone Mr Fox had left small time actor Billy Kat alone in his office while under hypnosis. However a rather curious young mouse walked in and started talking to the only person that seemed to be willing to pay attention to her on this busy day.

Which could certainly cause more than a few problems for Billy's newest role in an upcomming action adventure movie.
