The composer of the film's score, Arthur Rathbone Pullen, is the son of twice Booker nominated British author Julian Rathbone.
The film's dialogue is entirely in Urdu, it was made in Pakistan with Pakistani actors but was directed by a British film maker. Prior to making Tamanna, Steven Moore had been to Pakistan several times for documentary films but also worked in Lollywood with several famous local 'old school' directors studying the national and regional cinema.
Salman Shahid and Feryal Gauhar were both taken on for the roles in 2009, but the situation in the country and the lack of available equipment meant it took three years to get to production. In that period form 2009 until Tamanna'a release in 2014 there were only a handful of film's made in Pakistan, despite talk of a revival since the success of Mansoor's KKL in 2007.
The film's initial length was almost three hours, but after cutting scenes that might not get pass the country's strict censors, and a long opening preamble that was thought might not go down well with the audience in Pakistan, the movie was cut for pace. Included in the cuts was a scene in Wazir Khan Mosque with actor Rasheed Naz, and a long TV interview with presenter Sahir Lodhi.
