Mister John is a 2013 drama film by Joe Lawlor and Christine Molloy (who are also known by the name of their creative partnership - Desperate Optimists).

It was their second feature film following their debut Helen and stars Aidan Gillen, Zoe Tay, Michael Thomas, and Claire Keelan.

[3] Tim Robey of The Daily Telegraph rated it 4/5 stars and described Gillen's acting as a "major, moving performance" that stops the film from becoming pretentious.

[5] Guy Lodge of Variety described it as "a coolly composed, quietly impressive character study anchored by Aidan Gillen's tremendous performance".

[1] Stephen Dalton of The Hollywood Reporter wrote, "But despite some quality ingredients, Mister John never quite plumbs the hidden depths of poetic profundity it seems to promise.
