Jelly baby

Behind the scenes

 * On a number of occasions, the Doctor offered "jelly babies" when in fact having another kind of sweet, such as liquorice allsorts. For example; DW: The Sun Makers and Image of the Fendahl.
 * Tom Baker has claimed that the original script of The Face of Evil involved the Doctor threatening the tribesmen with a knife. Feeling that such an act was not appropriate, he insisted that the Doctor bluff his way out with a jelly baby instead.
 * In the United States, jelly babies had a low profile as a confectionery product. When Pinnacle Books published Doctor Who novelisations in new packaging, the editorial changes made by them included changing jelly babies to jelly beans, for fear of confusing American readers. Later, when the series had a great deal more popularity, many Americans simply associated jelly babies with Doctor Who and with the Doctor as played by Tom Baker. Under license from the BBC, one company sold jelly babies in packaging resembling the Doctor's TARDIS, advertising them as "the Cosmic Candy of the Time Lords".
 * The "Inside the TARDIS" featurette on the UK DVD of Doctor Who includes a closeup view of the bowl of jelly babies enjoyed by the Seventh Doctor at the start of the film.
