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 due to it only having three wheels.
Many TV themes by Howard Goodall were adapted from serious pieces of church choral music. Here, the title music "Ecce homo" ("Behold the man") was based on a few bars of "Locus Iste" by Anton Bruckner. New lyrics (in Latin) were written: "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 confirmed to be "Mr." throughout the TV series and the spinoff movies. There are several occasions where he writes his full name as "Mr. Bean" on registers or envelopes, or shows his printed driver's licence or passport with "Bean" in the Last Name slot and "Mr." in the First Name slot. (There used to be a rumour that one scene in a TV show or movie shows a passport giving his name as "Rowan" after Rowan Atkinson, but no specific citations or screen captures have ever been provided to back up this rumour, which probably isn't true. His first name is consistently "Mr.".)
At the beginning of Episode Two onwards, Mr. Bean falls from the sky in a beam of light, accompanied by a choir singing "Ecce homo qui est faba" (Behold the man who is a bean). These opening sequences were initially in black and white in episodes 2 and 3 and were intended by the producers to show his status as an "ordinary man cast into the spotlight". However, later episodes showed Mr. Bean dropping from the night sky in a deserted London street, against the backdrop of St. Paul's Cathedral. Atkinson himself has acknowledged that Bean has "a slightly alien aspect to him"; in the animated series, he is shown to be an alien.
Mr. Bean has more likes on Facebook than Britney Spears, and in a poll conducted amongst foreigners living in the UK in 2015 on famous British people; Mr. Bean was voted as being more recognisable to foreigners than Princess Catherine "Kate" Middleton, Duchess of Cambridge.
Due to the focus on visual jokes as opposed to verbal humor, the show was able to connect to a world-wide audience. In East-Asia, where it is not uncommon for people to also adopt a Western-sounding first name, the show was so popular that many boys adopted the name 'Rowan' in honor of Mr. Bean's performer, Rowan Atkinson.
The title sequence, which sees Mr. Bean drop down in a beam of light, gave viewers the impression that Mr. Bean is an outer space alien, or perhaps a fallen angel. The show's creators have never addressed the matter, preferring to leave it to imagination.
The title sequence, which depicts Bean falling from the sky in a beam of light to the sound of a heavenly choir, has led to speculation that the character might be a fallen angel. Rowan Atkinson appeared in Richard Curtis's film 'Love, Actually' as a character which Curtis originally wrote as an angel, though this detail was not used in the finished film.

In the final show of the series, Mr. Bean is seen put into a crate and shipped off to Moscow, Russia, but in the Bean (1997) film, Mr. Bean is back in London and now works as a caretaker at the National Gallery. It most likely, Mr. Bean may had got a flight or traveled on a ship back to the United Kingdom and had gotten employment by the National Gallery.
