The blue vehicle (whose occupant's identity is never revealed) that Mr. Bean encounters and causes to get into accidents in some episodes is a light blue Reliant Regal Supervan III. This model has a history of being highly unstable and easily tipped.
The title music "Ecce homo" ("Behold the man"), like many TV themes by Howard Goodall, was originally written as a serious piece of church choral music. New lyrics (in Latin) were written for "Mr. Bean": "Ecce homo qui est faba. Vale homo qui est faba" ("Behold the man who is a bean. Farewell the man who is a bean").
Mr. Bean's first name is never explicitly revealed, but in Mr. Bean: The Return of Mr. Bean (1990) it is alluded that his first name is actually "Mr.", as when he writes his birthday card at the restaurant, he writes "Mr." on the front of the envelope.
