Louise: (Her impressions on Tom Baker's attitude while she worked with him in Doctor Who) He was very dedicated to the part. He got very frustrated sometimes. He is really intelligent. He has a very, very high IQ and if he was dealing with people who didn't quite match that, he wasn't always the most tolerant person. His love and care and dedication to the programme never faltered, never failed. He really, really did work very hard at it and I think when he felt people weren't matching that he got frustrated.
