Mumbai: Popular anchor and comedian Sajid Khan, who turned director with hit film "Heyy Babyy", is known to be quite a perfectionist.

Recently, Sajid and his writer had a long brainstorming session to make one of their scripts interesting and innovative. So engrossed were they with their task that they ended up in a room for almost a week!

Said a source close to the filmmaker: "Sajid and his writer were holed up in a room for a week working on a script. But on the sixth day, something went wrong and the two started arguing."

The source added: "Sensing that something was amiss, his mother had to intervene and pacify them."
