It’s a US TV movie, the proper speed is 23.976fps/59.94i.
IIRC Doctor Who 1996 PAL uses a DEFT standards conversion which I describe here. I don’t know if they’ve changed that for later releases, but the native format of the movie is 59.94i so I suggest finding the highest quality NTSC source and starting there. You can IVTC most of that, but the special effects shots and credits will be 30 fps so you have to make a choice about how to convert those, and really should do those scenes separately to the rest of the film.
I think the original region 1 DVD release was converted from the PAL master so be aware of that, you may need to get the VHS or a broadcast recording to get the best version.
