Julia Jekyll and Harriet Hyde

Julia Jekyll and Harriet Hyde is a British children's television series which originally aired on BBC One in the United Kingdom between 1995 and 1998.

Plot
Julia Jekyll is the highly intelligent star pupil of the Rocket Academy, a school for gifted children. She develops a refreshing drink as part of a science project (her 'elixir'), however, the school bullies, Sharon and Nicola (known colloquially as the Blister Sisters; also the nieces of the science teacher, Mr. Blister), sabotage her project by adding a bottle of hair growth formula to the concoction. While presenting her project to the class, Julia drinks the elixir, and finds herself transformed into a monstrous creature, who she calls 'Harriet Hyde'. Ever since that moment, Julia has found herself unexpectedly transforming into Harriet Hyde at the most inopportune moments.

The series follows Julia's attempts to try and reverse the effects of the tainted elixir, and the various mishaps and adventures that occur as a result of her unexpected changes into Harriet Hyde.

Title sequence
The title sequence features a wooden board with the words 'JULIA JEKYLL' carved into it. A shelf below these words holds a beaker full of boiling green liquid. A hand picks up the beaker and brings it towards the camera. Cartoon smoke and sparkles appear as the camera is entirely focused on the green liquid. A puff of green cartoon smoke erupts, revealing the wooden board again, now joined by the letters 'and Harriet Hyde' in black ( 'and' ) and green ( 'Harriet Hyde'). A steady trickle of smoke pours off the newly-added letters.

The title sequence was designed by Pete Wane. The model background and lettering was made by Alan Kemp, and compositing for the title sequence was done by Malcolm Dalton in the BBC's 'Quantel Harry' effects compositing system.

Theme music
Based on the information available, there appears to be two variants of the opening theme. The only major difference is the adjustment of two notes; two D notes are brought up to E in the second variation. The second variation is the theme that features on all known archived copies recorded from television broadcasts. The first variation has been made available by way of the BBC Motion Graphics Archive.

It is possible that the copies of the episodes available online originate from repeat broadcasts which have been amended to use the second variant of the theme for the purpose of consistency (series one was repeated in 1997; four months after the conclusion of series two).

The show was supposedly well-received in China - if the program was indeed aired in China, it was likely broadcast as part of BBC Prime's Asian service. This means that Julia Jekyll and Harriet Hyde could have been aired in China as late as 2004/2005.
