Charlie Hunnam on Crimson Peak Set

Fans know him best as the tattooed bad-boy biker Jackson 'Jax' Teller on FX's Sons of Anarchy.

But Charlie Hunnam looked every bit the dapper Englishman suited up on the Ontario set of his new film Crimson Peak Thursday. The British thespian spent his 34th birthday shooting his role as Dr. Alan McMichael in the horror film set in 19th century Cumbria. Female fans young and old flocked around the clean-shaven 'man of mayhem' and he kindly obliged them with autographs and pictures.

In Crimson Peak, Charlie ditches his Harley-Davidson and reunites with his Pacific Rim director Guillermo del Toro.

Mia Wasikowska heads up the gothic romance as an author called Edith Cushing, who discovers her charming new husband Sir Thomas Sharpe (Tom Hiddleston) is not who he appears to be.

'[Crimson Peak] has moments that are very visceral, physical violence,' the Gravity director (fucking Daily Fail keeps referring to Del Toro as the Gravity director) told Screen Rant last year. 'You’re in this sort of sedate romance and then there is this brutal moment where you’re like, “Whoa!” And it has a lot of kinky moments.'

Coincidentally, Newcastle-born Hunnam is a graduate of Cumbria College of Art and Design, where he studied film and acting, but in Crimson Peak, Canada doubles for rural Northern England, and shooting on Thursday took place at a crumbling mansion.

The big-screen ghost story - due out October 16, 2015 - also features Jessica Chastain.

because we're on a Crimson Peak wave (still makes me think of my period)
