LOS ANGELES-Taylor Swift’s younger brother Austin has made his acting debut in the new Pierce Brosnan movie.

The 24-year-old has nabbed a part in the upcoming thriller I.T., starring former James Bond actor Brosnan, and was spotted in the recent trailer for the film, which is due out in September (16).

I.T. follows the story of a consultant-turned-hacker, played by James Frecheville, who tries to ruin a wealthy businessman (Brosnan) when their relationship turns sour - stalking his daughter and threatening his life.

While details of Austin’s role are currently unknown, eagle-eyed fans pointed him out in the recently released trailer for the film, around the 1 minute 30 second mark.

Shake It Off hit maker Taylor shared how proud she was of her younger brother last September (15) when she posted a photo of Austin on the set of the film.

“My brother @austinkingsleyswift just acted in his first movie and I’m all proud and stuff,” she captioned the shot.

The siblings are very close, and have supported each other through thick and thin. When Kanye West’s track Famous was released back in February, featuring disparaging lyrics about Taylor, Austin responded by filming himself throwing a pair of sneakers from the rapper’s Adidas collection in the trash.

In the clip he posted on Instagram, Austin grabs his $950 (£726) Moonrock Yeezy Boost 350 sneakers and puts them in the garbage. He captioned the video, “Getting a head start on some spring cleaning. Here we go again.”
