Alexander Stephen Hassell (born 7 September 1980) is an English actor. He is co-founder of The Factory Theatre Company. Hassell was born in Southend, England, the youngest of four, to a vicar. He trained at the Central School of Speech and Drama after completing GCSE and A-Level courses at Moulsham High School, in Chelmsford, Essex.
He has appeared in a number of stage roles, most recently as Hal in Henry IV Parts I and II, and Henry in Henry V, for the Royal Shakespeare Company.
