Dylan has credits as an assistant on films including Unforgettable, CHIPS, and Get Hard. 

Zac recently said he turns to his brother for advice on his love life, as his sibling has 'lived a more normal life than I did growing up.'   

'If I'm dating someone, one of the few people I need to weigh in on the situation is my brother,' Zac told Cosmopolitan in May. 'We live together, and we're different in a lot of ways, but he's really grounded.' 

Zac found fame in Disney teen movie High School Musical in 2006 after beginning acting at the age of 11.

Dylan went on to graduate with an Economics Degree from California Polytechnic State University in 2013.
