Actor Colin Farrell has checked himself into rehab as a "preventive measure", after reportedly feeling overwhelmed with projects and needing a break.

The Fantastic Beasts and where to Find Them actor has struggled publicly with addiction in the past, seeking treatment in 2005 for his substance issues after he wrapped the film Miami Vice.

Now a source close to Farrell has told People that the actor isn't drinking again, and admitted himself to the Arizona facility last week "because he needed a break".

"He put himself in there. It was voluntary... He's been sober 12 years and wanted to do this to make sure he stays that way," the source explained.

"He's taking some me-time and doing a tune-up and a reset. This was all his idea."

The source said Colin was "hyper aware" of his addiction and told friends he needed help.

The 41-year-old father-of-two opened up about his previous stint in rehab on The Late Late Show in 2013.

"Miami Vice wrapped... and I was put on a plane and sent to rehab," he explained at the time.

"I had quite a high tolerance for various drugs for years, I thought. It accumulated to the point where I couldn't put my foot on the brake anymore."

Farrell shares 14-year-old son James with ex-girlfriend Kim Bordenave, and 8-year-old son Henry with ex-girlfriend Alicia Bachleda.
