"'Joker' completes shooting in November. Then begins work on VFX and 3D. The wait will be totally worth it. Have patience. Big films take time," Kunder posted on his Twitter page.
The 38-year-old, who is married to choreographer-turned-director Farah Khan, says he wants to leave no stone unturned for his latest project.
"'Joker'is the first of its kind film. So every detail needs a lot of time and effort since it's being attempted for the first time. 'Joker' will release sometime in 2012. We are not rushing for it. I believe filmmaking is not a race. It's not a product. It's a work of passion," he added.
In the past, Kunder has edited films like "Main Hoon Na" and "Om Shanti Om". His debut directorial movie "Jaan-E-Mann" released in 2006.
The film is being jointly produced by Kunder and Farah's Three's Company and Akshay Kumar's Hari Om Entertainment Company.
