Daniel Radcliffe pranked the NYLON office hard in July. Now he’s taken us on a private tour of London’s Old Operating Theatre to discuss his new role in upcoming film Victor Frankenstein in which he plays Igor to James McAvoy’s Frankenstein. It turns out the actor (and hobbyist rapper) is full of surprises, revealing a secret Instagram account, specific superfan, relationships with former castmates and much more. Read the full interview from our November issue live now on NYLON.com.

Victor Frankenstein: “I like the fact that it’s a studio movie with these big sets and sequences, but there’s also a cool intellectual debate going on – our innate fear of technology and the fear of people who push it beyond where we’re comfortable with it going – it felt like a nice combination.”

He sticks to a uniform: He is, however, adventurous when it comes to socks – most of which his girlfriend, actress Erin Darke, buys for him. Today’s pair features a stripper dancing on a pole with money falling down around her…

Emma Watson’s HeForShe Campaign: “I think it’s fantastic that she’s bringing attention to it and adding to the conversation. I also find it bemusing, honestly, maybe because I have cool parents with a very equal marriage and have had good role models all my life, but I thought this was done.”
