Robert Cormier’s “Heartland” co-star Amber Marshall shared a touching tribute following the actor’s unexpected death on Friday. Cormier was 33.

Marshall took to Instagram on Wednesday to share several images with Cormier on-set of the family drama series. Marshall took on the role of Amy Fleming and Cormier played Finn Cotter, a potential love interest for Amy that was introduced in season 15.

“Robert was truly a joy to be around. He had an infectious smile, and such a big heart. He was especially kind and gentle with the animals on set, which goes a long way in my books,” Marshall began her Instagram caption.

“Robert, I am so thankful I was able to get to know you and work alongside you. You left us far too soon, but I promise you will always be remembered. #RIP,” she concluded.
