Tom Hardy's son was his "spirit guide" on 'Venom'

He told 'Entertainment Tonight': "He was pretty much in the driving seat for the most of it, and I did use him as my anthology and mythology wizard.

"He told me what I was doing wrong and I was doing more things wrong than I was doing right because children are deeply honest. He was my little spirit guide in that aspect. So as far as I'm concerned, I passed his [test], and that's the best I could do."

Tom - who also has a three-year-old child with wife Charlotte Riley, who is believed to be pregnant - had a great time playing Eddie Brock and his alter ego Venom in the movie and is hoping he'll be part of a franchise for "several years".

He said: "We went into this hoping to build it, and I went into it hoping to do something for the next several years and I can invest myself in.

"But we have to launch it and see how people feel about it, and if they don't like it, we'll see, but I don't think they will. I have a really good feeling about it. I know the whole team has poured a lot of love into it, and I've really enjoyed it. I've left a lot of stuff out there and I did a lot of improvisation in it that will never make it to the movie."

And the 'Dark Knight Rises' actor joked he's got a number of unusual ideas for future films.

He quipped: "There might be a singing and dancing number in there somewhere possibly in a sequel, because I think we should push the boundaries, maybe a little figure skating."
