In April this year, Lea Michele announced her engagement to her fiance Zandy Reich.

Cory Monteith was found dead at the Fairmont Pacific Rim hotel in Vancouver, Canada, on the July 13, 2013 when he was just 31-years-old. The coroner’s report classified the death as accidental, and said it was caused by a lethal dose of heroin and alcohol.

The tragic irony was that his passing came just months after he played a tortured drug addiction in McCanick.

Josh Waller, the director of the film – which was in post-production at the time of Monteith’s death –  told ET Canada that the young actor took the role to try to achieve closure.

“He said he wanted the role so badly because he had a very jaded past and he’d never been able to tap into that as an actor and kind of purge his system,” he said.

Australian actor Heath Ledger was also playing a “dark” part, The Joker in The Dark Knight, when he died in very similar circumstances in 2008.

Monteith had openly spoken about his struggle with drug addiction, telling Parade magazine in 2011 he would do “Anything and everything, as much as possible… I had a serious problem”.

When the actor was 19, his mother and his friends staged an intervention.

“That’s when I first went to rehab. I did the stint but then went back to doing exactly what I left off doing,” he said.

Monteith’s body was discovered after he failed to check out of his hotel room, where hotel staff found him unresponsive.
