Actress Karen Gillan says she is a "pretty awkward person" in real life.

The 29-year-old portrays commando Ruby Roundhouse in forthcoming film "Jumanji: Welcome to the Jungle", but she says in real life she is more like her alter-ego's avatar Martha Schwartz, who is a shy bookworm, reports dailymail.co.uk.

"Honestly, I'm Martha. I completely understand why I was cast in this role because I'm a pretty awkward person in general," Gillan told Virgin Atlantic's Vera Magazine.

"But I keep getting cast in these kicka** roles, so I just honestly feel like it's so close to my life," she added.
