acob Rook is an actor and producer from Watertown, South Dakota. In 2018, he worked with the production company Lausey Films as a producer and featured actor for both seasons of the hit web series, The Lausey Show (2019). For his role in the first season of The Lausey Show, Rook was nominated for a Best Actor award at the First Lausie Award Show but lost to his co-star Ben Griffin.

Following the cancellation of The Lausey Show, Rook released his directorial debut as a pseudo-spin-off of his earlier show in 2020's The Creature of Memorial Park. The short was set in the same world as his previous work but featured wholly new characters. In 2021 and 2022, Rook starred in a duology of improv-based comedy horror films entitled The Grooks and The Grooks II, respectively. For his role as Detective Rook in The Grooks II, Rook brought home his first Best Actor Lausie Award at the 2nd Award Ceremony.

Today, Rook has no official works in pre-production, but sources tie him to the film company I29 Entertainment, and he is rumored to be returning for The Grooks III.
