<P> Another additional scene with Donna was cut from the final episode: "There was an additional Donna bit after this goodbye from the Doctor, which is when he goes outside into the TARDIS, we cut back into the kitchen, and there's a moment where Donna hears the TARDIS...there's a moment of realisation, and then she turns back round and carries on talking into the phone ." Gardner considered this scene untruthful and too confusing, since Donna remembering would lead to her death, and since she didn't recognise the Doctor it wouldn't make sense to assume she would recognise the noise of the TARDIS . </P> <P> This episode's original ending involved the Doctor, following the final scene where he is alone in the TARDIS, being alerted to something on the monitor and as he checks two Cybermen rise up behind him . This was supposed to lead directly into The Next Doctor, but Davies was convinced by Benjamin Cook (who was corresponding with Davies for the book Doctor Who: The Writer's Tale) to drop the scene, as he felt that a cliffhanger was not appropriate after such a sad ending . </P> <P> Castell Coch, situated minutes away from Doctor Who's Upper Boat Studios, is used as the German castle . The beach at Southerndown, a few miles west of Cardiff, is used once more as Norway's fictional Dårlig Ulv Stranden (Bad Wolf Bay). </P> <P> Some exterior scenes, including various companions interacting with Daleks, were shot at Arcot Street, Penarth . </P>
