; May 11, 1982 – July 13, 2013) was a Canadian actor and musician, known for his role as Finn Hudson on the Fox television series Glee.As an actor based in British Columbia, Monteith had minor roles on television series before being cast on Glee.
The following year, he made a brief appearance in Urban Legend: a Bloody Mary. Canadian director Gia Milani's film All The Wrong Reasons stars Monteith as "a big box department store manager whose wife is struggling with post-traumatic stress disorder." Milani suggests he was excited to play his own age, in a "heavy role." He filmed his part on weekdays, flying to Los Angeles on weekends to do promotional work for Glee. Series creator Ryan Murphy took notice of the video, but pointed out that he had to be singing, as auditioning actors for Glee with no theatrical experience were required to prove they could sing and dance as well as act. Not only for Glee, but for anything in life." Finn is the star quarterback of his high school football team, and risks alienation from his friends by joining the school's glee club.
Monteith said of his casting process, "I was like a lot of kids, looking for something to be interested in. He is a popular jock at the top of the school's social hierarchy, but when forced to join the glee club, he finds he loves it.
After consultation with Michele, who also plays Monteith's love interest on Glee, showrunners postponed production of Glee's fifth season to August rather than late July.
Consequently, the season premiered a week later than planned.
The Vancouver Police Department stated that the cause of death was not immediately apparent, but ruled out foul play. It noted that Monteith also had codeine and morphine in his system at the time of his death, and that he was found with drug paraphernalia that included a spoon with drug residue and a used hypodermic needle, as well as two empty bottles of champagne.
The coroner wrote that Monteith had experienced intermittent periods of drug abuse and abstinence throughout his life, and that "after a period of cessation from opioid drug use, a previously tolerated drug concentration level may become toxic and fatal." On July 25, Michele and Glee creator Ryan Murphy held a celebration of life for Monteith in Los Angeles, attended by cast, crew, and creators of the show, as well as colleagues from the show's network and studio.
On July 13, 2013, he died of a toxic combination of heroin and alcohol in a Vancouver hotel room.
After the divorce he saw little of his father due to Joe Monteith's military service, and he had social difficulties at school.
Commenting on the fifth episode of the first season, Eric Goldman of IGN wrote, "We got to see a bit of a darker side to Finn [...] it's good to see this, because up until now, Finn's been a bit too strait-laced to totally invest in".
In the second season's eighth episode, "Furt", Tim Stack of Entertainment Weekly noted "It's been a while since we've gotten some Finn focus, and I think I just missed Cory Monteith.
Following his success in that show, Monteith's film work included the movie Monte Carlo, and a starring role in Sisters & Brothers.
