Michelle Fowler
Michelle Fowler (also Holloway) is a fictional character from the BBC soap opera "EastEnders", played by Susan Tully from the first episode in 1985 until the character's departure in 1995. In December 2016, it was announced Michelle would be returning to the show after 21 years, with actress Jenna Russell taking over the role making her first appearance on 24 December 2016. In her first stint Michelle made some huge mistakes during her time in Albert Square mainly through having a habit of choosing the wrong men and her stubborn nature meant that she rarely accepted help or listened to good advice. Being determined and outspoken, she has never been afraid to defend herself or her beliefs. Since the recast to Russell in 2016, Michelle's storylines have revolved around her having had an illegal relationship with her student, Preston Cooper (Martin Anzor) in America, a love triangle involving her niece Bex Fowler (Jasmine Armfield), crashing Phil Mitchell car into the local chip shop and being stalked by Tom Bailey (Daniel Casey). Russell's departure from the show was announced in March 2018, and Michelle departed on 17 April 2018.
Rose Tyler
The British media had regularly released conflicting reports about how long Piper would be staying with the programme. In March 2006, she claimed that she would continue on "Doctor Who" into its third series in 2007. The BBC announced on 15 June 2006 that Piper was to depart in the final episode of the second series, "Doomsday". Piper's decision to leave had been taken a year previously but remained a secret until news of her departure became public. Following "Doomsday", Piper as Rose was greenlit to be the star of the spin-off series "", set in her parallel universe and to air as a bank holiday special, but Davies deemed the concept "a spin-off too far" after "Torchwood" and "The Sarah Jane Adventures". Piper's eventual return during series four was planned during filming of the second series; in January 2006, she made a pact promising to return to film several more episodes. Davies and Piper cited her commitment to other projects—specifically, her roles as Belle de Jour in "Secret Diary of a Call Girl", the lead character in the BBC adaptations of Philip Pullman's Sally Lockhart quartet, and Fanny Price in the ITV adaptation of "Mansfield Park"—as explanations behind her departure appearing permanent. Davies' successor as executive producer, Steven Moffat praised the creation and casting of the character in advance of the series' 50th anniversary in 2013. He stated that the character of Rose helped secure the return of the show by allowing "an audience who would not naturally have watched "Doctor Who"" to become invested in the show. Moffat suggested that during the first two years of the revival "Doctor Who" "was Billie Piper’s show" and that this has given her an "iconic status" above other "Doctor Who" companions.
