Ryan Grantham had appeared in hit films Diary Of A Wimpy Kid and The Imaginarium Of Doctor Parnassus before landing a starring role in the hit series Riverdale – but then he committed a horrifying crime and will spend the rest of his life in prison
From an early age, Ryan Grantham showed promise as an actor, and soon opportunities were heading his way. His career started when he was only nine and at school in Vancouver, Canada, and like many young actors he appeared first in an advert before moving on to bigger roles.
In an episode of US show Supernatural, he played a kid who turns his superpowers on bullies. He also had roles in American TV series iZombie and movie The Imaginarium Of Doctor Parnassus.
After a notable part in the 2010 film Diary Of A Wimpy Kid, he got his big break in The CW show Riverdale, a teenage horror series based on characters from Archie Comics.
Actors Lili Reinhart and Cole Sprouse found fame in Riverdale, and the show put Grantham firmly in the spotlight. He played Jeffery Augustine, the hit-and-run killer of Fred Andrews, played by Luke Perry, who died of a stroke in 2019.
