The actor plays Bart McQueen in the Channel 4 soap, who has already been involved in a stabbing and a sex change plot since arriving in the village.
"I've got this big storyline coming up in Hollyoaks, which should be exciting and quite controversial. I really can't wait to nail the performance," Clarke told i-D.
Speaking of how he landed a role in Hollyoaks, he added: "I basically was really bad at school, just got really bad grades. I knew I needed to earn a living and I knew I wanted to be an actor, but I wanted a certain skill so I could earn money whilst I was doing it. I thought hairdressing maybe.
"I went to my Dad who got me an agent and I got a job doing a viral thing for a university and then an audition came up for Hollyoaks a week later. I just went to audition and then on the drive back home with my Mum they said I got the part."
Clarke recently admitted that he was "so nervous" about filming Bart's shock stage invasion at a Wretch 32 concert in London last year.
