Dylan O’Brien has dished about his toe-sucking scene with James Sweeney in Twinless.

Attention! Major, we repeat, major spoilers ahead!

Written and directed by Sweeney, the film follows two young men, Roman (O’Brien) and Dennis (Sweeney), who meet at a support group for people who have lost their twin. As they bond over their shared circumstance, the pair form an unlikely – and intense – friendship.

The synopsis adds: “Roman and Dennis both search for solace and an identity without their other halves and soon become inseparable outside the group. But when Roman meets Dennis’ ebullient co-worker Marcie, all is revealed to be not what it seems, as each man harbours secrets that could unravel everything.”

Twinless also stars Lauren Graham (Gilmore Girls), Tasha Smith (Survival of the Thickest), Chris Perfetti (Abbott Elementary), Susan Park (Snowpiercer) and Cree Cicchino (And Just Like That…).
