Will Smith thinks the sleight-of-hand moves in 'Focus' will fool cinemagoers.

The 46-year-old Hollywood actor - who stars alongside Margot Robbie, 24 - plays the role of conman Nicky in the romantic comedy-drama film and says that some of the tricks performed in the movie are sure to keep audiences hooked.

Speaking at the UK premiere of the movie in London's Leicester Square, he told BANG Showbiz: ''I think the level of the cons are ridiculous.

''There's a scene in the middle of this movie that's going to be the signature scene of this film. And it's a magnificent con that just creatively and artistically, people are going to love being fooled in a movie theatre.''

Will learnt the sleight-of-hand tricks from Las Vegas theatrical pickpocket Apollo Robbins, but he confessed that his talents pale in comparison.

Asked how his skills match-up to the expert, Will said: ''Apollo is a master. I've got none of that stuff. I can't do it.''

Apollo designed sleight-of-hand moves that have never been seen before on film, according to producer Denise Di Novi, who said he's been ''a tremendous resource both technically and creatively during this process''.
