British actor Daniel Radcliffe has revealed he loves making inappropriate jokes on set.

Popular 26-year-old actor who stars opposite fellow Brit James McAvoy in ‘Victor Frankenstein’ and has revealed that in a bid to cure his own on-set boredom, he’d resort to making vulgar jokes.

Daniel – who plays the part of Igor Strausman in the new movie – shared: ”I’m constantly trying to find jokes in things, even if it’s not appropriate.”

Meanwhile, James revealed that he and his co-star would often improvise while filming, even though most of their best efforts haven’t made the final cut of the horror movie.

The 36-year-old star told TotalFilm: ”A lot of it gets cut, but for every 10 pieces of s***e ad-lib that gets cut, you might just get half of one in. It’s worthwhile doing, just to get those.”

And James recalled one particularly juvenile on-set prank in which he defaced a piece of artwork.

He said: ”The art department drew the most beautiful, vascular arterial picture of the monster. And I’m pretty sure we drew and extra dong on it. But like a proper rubbish extra dong.”
