Alfred Molina plays evil Dr Octopus in the new blockbuster Spider-man 2.
He got rid of all his extra arms and met up with Adam from NR Showbiz.
You can catch the full interview on NR Showbiz as part of our Spider-man 2 special on Saturday 17 July on the CBBC channel.
Dr Octopus is a pretty nasty bad guy - How evil is he?
He's above nine, definitely above nine - on a scale of 1 to 10!
How did they make the arms look so real?
It was some animation and computer graphics and sometimes the tentacles were strapped onto me - all the close ups all the tentacles were on me and manipulated by puppeteers.
Was it hard working with them?
I thought it was gonna be distracting but they were actors too and they gave the tentacles lots of personality!
