There’s no greater tribute to him than that marvellous scene. And, a 93 year old in a wheelchair, acting until the very end of his life in a prime time BBC One show. He was even at the readthroughs, there’s footage in Doctor Who unleashed. The man was an absolute star. And all hail the great RTD for making this happen.

In unleashed we saw him standing up, so I think the wheelchair was just a prop to fit the narrative of him having been moved to a care home.
