Farren worked his way through all the visual arts in 2008, starring in The Man In The Attic with the Sydney Theatre Co., the film Lucky Country, and the Seven Network television series, All Saints. In 2012, he earned a starring role in Jennifer Lynch's film, Chained, playing "Rabbit", a boy enslaved and raised by a serial killer played by Vincent D'Onofrio. Farren said, "... Shooting the film felt like second nature, the scenes would be focused but loose, incredibly tense but hilarious.I never had to say too much to her [Lynch], she would give me a look or whisper one word and I'd get it."
