Immediately after '' Perfect Sense '' , Mackenzie directed the comedy musical '' You Instead '' ( 2011 ) released as '' Tonight You 're Mine '' in the US starring Luke Treadaway and Natalie Tena . Astonishingly it was filmed over four and a half days at the Scottish music festival T in the Park in 2010 where the cast and crew had to adopt a kind of guerrilla filmmaking approach to shoot amidst the chaos of a music festival alongside over 100,000 revellers . It premiered at both T in the Park in 2011 and at Austin 's SXSW
