From the DVD Commentary with Julie Gardner [executive producer] and Matthew Graham [writer]
Julie Gardner: I love this finger-in-jam moment. I remember seeing it on the rushes and just loving it.
Matthew Graham: Well that’s how it goes with this show. One minute the Doctor is saying, “There’s a terrible evil in your house and I’m here to help,” and the next minute he’s eating your jam, and being ticked off for it.
JG: I remember at one point, in one draft of the script, there was a big discussion about whether we should see the Doctor and Rose asleep overnight, because they are trapped in this house. And I was very, very keen on that because that’s something we’ve never seen before, and I think Russell and you both said, “Actually, no - we’ve got to keep the energy going, and given what’s happening he’s never going to be off-guard.”
MG: Do you know what, it would have been a really nice scene. The thing is, we probably would have cut it out at this stage
JG: Because you’d want to keep moving. Absolutely. Oh, all these nice ideas that never make it in.
