 Desmond Llewelyn (qv) was not the first choice for the role of Q.  Peter Burton (I) (qv) preceded Llewelyn as Q but for only one  film, _Dr. No (1962)_ (qv). In that movie, he was known as Major  Boothroyd and Armourer. Llewelyn was only referred to as Major  Boothroyd once in the James Bond movies, and that was by  Roger Moore (I) (qv) in the _Spy Who Loved Me, The (1977)_ (qv).
