Sean Cronin was born in West London to an English mother and an Irish/Welsh father but has both Spanish and Sicilian in his bloodline. Destiny struck in the early nineties and Sean was badly bitten by the film bug. Due to his intense and menacing presence Sean was asked to play supporting roles in films like 'James Bond, The World Is Not Enough' (1999), 'The Mummy' (1999), 'The Mummy Returns' (2001), 'Harry Potter and the Chamber of Secrets' (2002) and 'Fantastic Beasts and Where to Find Them' are just a few. Moving inevitably from the background to the foreground he more recently plays terrifying vampire 'Cyrus' in 'The Thompsons' (2012), sequel to the Hollywood Vampire movie 'The Hamiltons' (2006) by the 'Butcher Brothers' and in 'London's Finest' (2014) 2012 he plays crazy Russian gangster 'Dellski' and in 'The Callback Queen' (2013), he plays 'east end' gangster 'Arry' and 'Jacob' in 'The Brother' (2013) and 'Masked Syndicate Man' in 'Mission: Impossible - Rogue Nation' (2015) lead villain, Kane, in 'Kill Kane' (2016) another lead villain 'Thorn' in Neil Monahan's political horror 'Election Night', head of the Russian Mafia 'Igor' in Fraser Precious's brilliant crime thriller 'Safeguard' and more recently, lead super-villain 'Smiley' in 'Rendel: Cycle of Revenge', head vampire 'Madison' in his very own 'southern fried' vampire road movie 'Bogieville' and yet another 'very twisted' lead villain, 'Admiral Smee' in Lars Janssen's horror re-imagining of a classic, 'Captain Hook: The Cursed Tides'. In parallel, because of his love for all things film, he became a cinematographer and director in his own right shooting dozens of high end music videos, short films, and several features including 'Throw of a Dice' (2012). Sean also directed the award winning 'An Unfortunate Woman' (2015) beautiful period drama 'Irongate' and the award winning heart rending semi-biopic life story of disabled Paul Hodgson 'Give Them Wings' (2021) followed closely by yet another award winning human interest story 'Our Kid'. Sean has also dipped his directorial toe into the horror genre with two very different vampire movies 'Bogieville' and 'Drained', both set for release early 2025 but Sean's most prolific and biggest budget directorial exploit is 'Michael' - The Michael Watson Story' which goes into production spring 2025.

Sean has developed his craft both in acting and film making and is well as being an eclectic and talented film maker he is fast becoming one of the most convincing and sinister 'adversaries' in modern day cinema.

Sean has his own production company 'Magnificent Films'.
