Armie Hammer feared he was ''done'' after tearing a chest muscle.

The 'Call Me By Your Name' actor was left in agonising pain at the beginning of the year when he suffered the excruciating injury while working out, and after having surgery, he was trussed up in a sling for five months, which left him in a ''dark place'' as he feared for what it meant for his career.

He recalled: ''I went to a dark place: 'You're done. You've peaked.' ''

The 31-year-old actor - who has children Harper, three, and Ford, 10 months, with wife Elizabeth Chambers - admitted he relieves the accident in his ''nightmares''.

He said: ''I tore my pectoral muscle lifting weights. I can still hear the sound in my nightmares.

He recalled how his right arm ''drooped, like, totally flaccid'' and he then lifted his shirt and looked int he mirror, where he saw that his ''chest muscle had just shot to the middle of [his] torso.''

He added: ''There was a hole where the pec used to be.''

Armie was then stricken by nausea and severe pain, prompting to call his spouse, who was just days away from giving birth to their son, for help.

He quipped: ''I'm like, 'Wife!' Wife!!! I need ice!' Then I'm like, 'And a bowl! I'm going to be sick!' ''

But the 'Lone Ranger' star is relieved to have made a recovery much quicker than he expected.

He told the Hollywood Reporter: ''[It's] so much better. I found a really good physical therapy place that got me back in four months. They said it would take a year.''

Meanwhile, Armie admitted it was ''incredibly liberating'' being friends with Elizabeth - who had a boyfriend when they met - for three years before they got together.

He said: ''It was like, 'I don't have to impress you. I'm going to tell you everything. I'm going to tell you if I slept with somebody. If I took drugs.' We became closer, until one day I said, 'You have to break up with your boyfriend so we can start dating.' ''
