Born Elliott David James Brennan in Birmingham, England, on August 30, 1990. Brennan attended Whitesmore Secondary School, and pursued A-Levels at Grace Academy Solihull.
From the age of 7, Brennan had a passion for football, and wished to play professionally. He was a goalkeeper for a local team Chelmsley Town Football Club. Brennan was scouted by various professional clubs, and when he was 16, he signed a contract with Walsall FC. This was short lived as the pressure from academy football caused Brennan to lose passion for the game.
Brennan got into acting when he was 15, when he was cast in a school production of 'The Little Shop of Horrors', he was commended greatly on his performance and decided this was a career he wanted to pursue.
Grace Academy Solihull accepted Brennan in their Sixth Form where he got his A-Level in Drama. He then went to to the University of Northampton in pursuit of a degree in the same subject.
