According to the I Am Legend star, maths and science were always his strongest subjects.

“I always dreamed of designing a fully computerised classroom,” he told free London paper The Metro.

“You could come in and take roll call with fingerprints and then there’d be a keyboard built into the desk and as the teachers talked, their words would come up on a computerised board.”

And according to Mr Smith, it could still happen.

“I dreamed of building and creating something like that when I was a child and I may still do it,” he said.

“I’ve always loved the idea of connecting technology and education.”
