His Babylon 5 (1993) character, Michael Garibaldi, was once merchandised as a Halloween costume. Jerry Doyle was delighted with the idea.
When he applied for the part of Garibaldi on Babylon 5 (1993), he fluffed up his resume by claiming to have been a part of the Harlem Ballet Group. There was no such organization.
