Doctor Who star Matt Smith has claimed that the show's upcoming mid-series premiere is the best episode yet.
The actor praised Steven Moffat's 'Let's Kill Hitler' at the recent Television Critics Association press tour.
"I think 'Let's Kill Hitler' is maybe my favourite episode to date," he said. "It just rockets along."
Smith also promised that mysteries introduced in the first half of the sci-fi drama's sixth run will be resolved in future episodes.
"We've still got to understand just what happened to the Doctor in episode one," he hinted. "Steven [Moffat] has always delivered the payoff to all these revelations, in a way that is exactly what you would want it to be. It doesn't disappoint."
[SPOILER ALERT] Highlight to read.
Smith's co-star Karen Gillan recently revealed that 'Let's Kill Hitler' will feature a "really cool robot villain".
"It goes back in time and fixes people that have done [something] wrong in history," she explained.
