The youngster has been recognised for his work in the drama with a Best Supporting Actor nod, and he admits all the critical acclaim the film has received has really caught him off-guard because he wasn't mentally prepared.

"When I was auditioning, and even when we were filming the movie, I didn't really envision a world past the making of it," he confessed to U.S. network ABC on The Oscars red carpet. "I didn't even anticipate it coming out 'cause the second we finished (filming), I went away to college and I was so excited... I got into my favourite college with my three best friends and there was so much going on and then halfway through my freshman year, we went to Sundance (Film Festival) and I was like, 'Woah, this is a bit weird,' and then every month there's been some sort of new thing that's happened, and then this is the final chapter, and it's crazy being here."

Lucas has been taking some off his studies to promote the movie during awards season, but he is planning to head back to the University of North Carolina School of the Arts as soon as he returns home from Sunday's (26Feb17) Oscars.

The New York native shared, "I'm hoping to go back (to school) actually, after this, and spend some time there and just see all my friends."

Lucas' appearance at Hollywood's big night wasn't his first - he previously attended as a guest of his father, screenwriter Peter Hedges, back in 2003, when he was nominated for About A Boy, so the young actor had his own agenda as he attended the ceremony at the Dolby Theatre.

The star said, "We were looking at the photo album we had from 13 years ago when... my brother and I came with him when he was a nominee, and we're gonna recreate some of the photos we took from that weekend 13 years ago, so I'm excited for that."

Lucas will face tough competition for the Best Supporting Actor award - Dev Patel (Lion), Jeff Bridges (Hell or High Water), Michael Shannon (Nocturnal Animals) and category favourite Mahershala Ali (Moonlight) are all also up for the honour.
