'Fantastic Beasts' actor Eddie Redmayne on his favourite 'Harry Potter' film and novel

Actor Eddie Redmayne says his favourite Harry Potter film is Harry Potter and the Deathly Hallows.

The 34-year-old Oscar-winning actor, who will soon be seen in JK Rowling's fantasy drama Fantastic Beasts and Where to Find Them, said Daniel Radcliffe was amazing in the movie, reported Entertainment Weekly.

"With the last two, they had something I kept rewatching, going back and watching Ralph Fiennes and Daniel Radcliffe do that extraordinary duel. When you're (casting spells on set), the effects of this huge tension of what's coming out of your wand is put (into the shot in post-production, you're) literally acting with nothing, and I found it so operatic and deeply moving. I found it so climatically satisfying," Redmayne said.

However, Harry Potter and the Philosopher's Stone, is the actor's favourite book from the series.

"I suppose I'd go with the first. My little brother, when he was 6 years old, he would always read it, and it had that instant immersion into the world that made you release your imagination."
