American-born star Daniel Wu feels "schizophrenic" juggling the dual roles of leading man and producer for his latest movie Control.
Speaking to reporters here over the telephone from his home in Hong Kong yesterday, he says: "As the actor, I want more time for filming to re-take the shots that I think can be better.
"But as producer, I've to make sure we finish filming on time so that we don't go over the budget. So I definitely felt schizophrenic all the time."
Control, which opens in cinemas next Thursday, is a noirish thriller about an insurance sales agent named Mark (played by Wu) whose life is turned upside down when a mystery man starts calling him and forcing him to commit crimes.
Wu, 39, adds with a laugh that taking on both roles means there is no time for rest. "When you're an actor, you can go home and rest as soon as you're done with your scenes. But as the producer, I have to stay back to make sure everyone on set is okay and whether they want any food. It was really quite tiring."
This is not his first time as a producer. He was a producer of films including martial arts flick Taichi 0 (2012), mockumentary The Heavenly Kings (2006) and mystery drama Night Corridor (2003).
But Control is the first project in which he was fully involved "from beginning to end".
He says: "As soon as I got hold of this script, I was hooked on the story and really wanted to get the film made. I was more involved in this than any other film before. It was just such an intriguing story and I wanted it to be different from the usual movie in the Chinese film industry."
Directed by Hong Kong film-maker Kenneth Bi, Control also stars Chinese actress Yao Chen and Hong Kong stars Simon Yam and Kara Hui.
Adds Wu: "My company Diversion Pictures is always looking to make movies that look and feel different, and Control is definitely like that."
His film production company, set up in 2011, is co-owned by actor-director Stephen Fung, 39.
Asked how the two friends collaborate as work partners, Wu says they have managed to "find the perfect balance".
