Rishi Kapoor is known in the industry for his infamous mood swings. And the cast and crew of his upcoming film recently had to face his wrath

Sources say that thanks to a technical glitch in one of the film's shots, the veteran actor lost his cool and even didn't spare his co-star Sonam Kapoor.

Says an insider, `After a particular shot, director Nupur Asthana realised there was a sound error and the scene had to be re-shot. As soon as he heard it, Rishi completely lost it and even started shouting. He ended up snubbing Sonam too.`

Says a source well versed with Rishi's mood swings, `Everyone on the sets was on high alert as Rishi gave a re-shot. No one wanted his bad mood to return. He is known to be very temperamental and there is hardly any day when he doesn't get angry.`

Past imperfect
Rishi has also been known to lose his cool at media persons on several occasions. On one occasion he even threatened to `fix` journalists who came close to him. On another occasion when reporters dished out questions regarding son Ranbir, the veteran actor refused to face the cameras until the `offenders` left the spot.
