Radcliffe proves an assured actor and makes a perfectly able equimaniac. He can do aggression and pain, and, oddly, is lacking only in the sense of magic and wonder the part demands.
though gripping and theatrically skilful, Equus is at root dated, pretentious and even a bit pernicious, much like the 1960s guru who clearly influenced Shaffer.
There is an interview of Dan and Richard Griffiths (who plays Uncle Vernon), telecasted at CNN last night.
