Over the weekend, my buddy pal Laurie was surprised to learn that Michael is working on Frank because she and her husband love Frank Sidebottom. They never saw him live, but enjoy his work and lived near him when they lived in England. They are also planning on visiting Sidebottom/Chris Sievey's memorial statue in Timperley this summer. So needless to say, they were both floored when they learned that Fassy is portraying Sidebottom in 'Frank', and they said it's pretty awesome that an actor of Michael's caliber is playing him.
Here is an image of Chris Sievey, he was a handsome man.
So it's not so far fetched that an equally handsome man like Michael has covered up his head for art.
