 * 26 and 27 - A two-part special episode, Dimensions in Time, is broadcast to mark the 30th anniversary of Doctor Who. Presented as part of the Children in Need campaign, the episodes were produced in 3-D and featured all surviving Doctor actors and many surviving companions, as well. The special marked the final on-screen appearance of Jon Pertwee as the Doctor, was the only Doctor Who story written by John Nathan Turner, and it was also Turner's final involvement with the franchise. Rejected as canon by Who fandom, the special was produced in lieu of an abandoned movie project, The Dark Dimension. The special episodes feature a new, sped-up arrangement of the Doctor Who theme, and use a variation of the opening credits sequence introduced in 1987, along with the series logo also from '87; it is the final on-screen use of both.
