Mike Egan, the man who advised Bill about polio

Mike Egan, a native of Leicestershire UK, was diagnosed with polio at the age of 4. He's had to live with the condition his whole life, needing full-leg calipers and crutches to walk and move around similar to FDR. Mike served as an adviser to Bill Murray on the set of Hyde Park on Hudson, teaching him how to portray a person who is afflicted by polio.
