After "Perfect Sense", Mackenzie directed the comedy musical "You Instead" (2011) as "Tonight You're Mine" in the United States. The film stars Luke Treadaway and Natalia Tena as two rival rock stars who get handcuffed together for 24 hours at a music festival where they're both due to perform. It was filmed over five days at the Scottish music festival T in the Park in 2010. The cast and crew had to adopt a kind of guerrilla filmmaking approach to shoot amidst the chaos of a music festival. It premiered at both T in the Park in 2011 and Austin based music and film festival SXSW.
