Colin Baker (contracted for four years starting in 1985) was originally due to reprise his role as the Sixth Doctor prior to his dismissal at the request of Michael Grade, who said that a 24th season would only happen if a new actor took the title role. Baker was offered the chance to film a single four-part story ending in his regeneration, but he declined (as he did not want to miss out on other work in the meantime), instead offering to do the entirety of the season and leave the show at its conclusion. The BBC never responded to his letter. Had Baker reprised his role, a story featuring the Sixth Doctor and Mel properly meeting for the first time was going to open the season.
A new logo for the series was introduced with this season along with a new opening credits sequence that moved away from the "starfield" motif introduced in 1980, as producer John Nathan-Turner thought it was time for the series to have a brand new look. As with the opening sequence from the Sixth Doctor era, the Seventh Doctor's opening does not use a static image of the Doctor, but rather one with limited animation: the image of the Doctor starts as a scowl, then fades to a wink followed by a smile. McCoy wears makeup that gives his face and hair a silver/grey appearance. Episode four of Time and the Rani mistakenly uses an early version of this sequence, which gives the Doctor's face a shadowy look which producer John Nathan-Turner felt was not prominent enough.[1][2]
Music
Keff McCulloch arranged the new opening theme. It was used until the end of the regular run of the series. The new theme arrangement marked the first time since the early part of the Second Doctor's era that the theme's "middle eight" section was regularly heard during the opening credits (the previous two arrangements used the middle eight during the closing credits only).
The departure of Bonnie Langford saw plans to introduce a new companion. However, owing to Langford being undecided as to when she would actually leave the show, producer John Nathan-Turner asked writers Malcolm Kohll and Ian Briggs to formulate characters that could be used as potential companions. Kohll designed a character in his script, titled The Flight of the Chimeron (eventually to take shape as Delta and the Bannermen), called Ray. Initially, it appeared that The Flight of the Chimeron would be the final serial of the season, which would see Ray leave with the Doctor. However, by the time it came to production and scheduling for the season, Kohll's serial had been swapped in the running order with Ian Briggs' (which became Dragonfire), and led to Briggs' creation, who eventually became Ace, taking Mel's place with the Doctor.[citation needed]
Andrew Cartmel takes over as script editor. This season is moved to a Monday schedule.
The previous season, while ostensibly a single 14-part serial, was divided into three stories of four episodes and one of two episodes. For this season, this was re-jigged into a new format that would be followed over the next three years, with a pair of four-parters and a pair of three-parters. Not including The Two Doctors, which had episodes of 45-minute duration, Delta and the Bannermen was the first standard format (25-minute) 3 part serial since Planet of Giants in Season 2.
The Rani lures the TARDIS to Lakertya, where she requires the Doctor's aid to complete a device which will draw on the intelligence of history's greatest geniuses to help her reshape the universe to her own design. To this end, she drugs the newly regenerated Doctor and masquerades as Mel to gain his trust. The real Mel, however, allies herself with the native Lakertyans, who have been suffering under the rule of the Rani and her bat-like Tetraps. It is up to Mel to rouse the Lakertyans to rebellion, and free the Doctor from the Rani's clutches.
The Doctor and Mel go to Paradise Towers for a holiday, only to find the famed complex in ruins. Long ago, the adults went off to fight a war and never returned. Left behind are the Kangs, gangs of wild teenaged girls; the Rezzies, cannibalistic old women; the Caretakers, who ostensibly look after the Towers; and Pex, who was too scared to go to war. But also lurking is Kroagnon, architect of Paradise Towers, who has taken mental possession of the Chief Caretaker and the cleaning robots in an attempt to rid his creation of human life forever.
The Doctor and Mel win a vacation on a time-travelling tour bus to a 1950s holiday camp. Also on the bus is Delta, the last of the Chimeron race, who is being hunted by the genocidal Bannermen and their brutish leader, Gavrok. When a mercenary on the bus alerts Gavrok to Delta's whereabouts, it is up to the Doctor and Mel to stop the assassins and find a way to give the Chimerons a new lease on life.
The TARDIS lands on Iceworld, an enormous shopping complex on Svartos. There, the Doctor and Mel meet up with a time-displaced teenaged waitress from Earth named Ace and their old friend Sabalom Glitz. Glitz is searching for the treasure of the legendary Dragon who is supposed to dwell beneath Iceworld. But when the Doctor joins Glitz in his quest, they discover more than they bargained for, unearthing the millennia-old secret of Kane, Iceworld's murderous ruler.
Broadcast
The entire season was broadcast from 7 September to 7 December 1987. Transmission for this season moved to Monday nights. In this way, BBC1 scheduled it against Coronation Street on ITV, ensuring ratings struggles.[5]
