If anybody thought passing years is a curse to mankind, Hema Malini and Shatrughan Sinha's behavior on the sets of Sony TV's 10 Ka Dum would come as a pleasant surprise.

Says our source, "Hema Malini and Shatrughan Sinha were so enthusiastic, it was infectious! During a segment similar to rapid fire rounds…both of them were as quick as school kids. Not just their energy, but their laughter and banter about the old days made the whole atmosphere charged with fun."

There was even a cool section of dialogue delivery. Says the source, "Hema Malini delighted the audience with her dialogues as Basanti from Sholay. It was breathtaking. She still had the same aura of mischief mixed with innocence."

Shatrughan Sinha on the other hand proved that his brains are just as sharp as good old days of youth. According to our source, "He raced through a long tongue-twister of a dialogue from a film he had done 30 years ago!"

Apparently Shatrughan also flaunted the attire he had worn for the evening. Our source says, "Shatru took pleasure in explaining the fact that his black suit with red scarf is his latest 'Jinnah' look."

We just hope that his 'Jinnah' look does not hurt his political career!
