Sandra says George is a better rapper.

The co-stars would fill slow periods while shooting the space movie by learning the lyrics to Rappers Delight by The Sugarhill Gang. They would then compete to see who could perform the song with the least mistakes.

Sandra says George was the better rapper – but definitely not perfect.

“I’ve got to give it to him,” Sandra said on LIVE with Kelly and Michael on Thursday. “There’s a couple words – the bridges – that I chose not to learn. I’ll give it to George. George has about 98 per cent of that song down, in the eight minute version.”

Rapping isn’t the only thing the two friends have in common. Sandra, 49, says she and George were “separated at birth”.

This made portraying two people with a strong emotional connection very easy in Gravity.

“It’s really about this emotional ride that you are allowed to step on,” Sandra revealed. “And whatever’s happened in your life, you experience that and think about, ‘What would I do?’”

According to Sandra, the movie is inspirational and should make people want to take chances in life.

“And hopefully by the time you get out of the theater, you go, ‘I’m going to change my life. I’m going to change and do the things I always said, ‘Maybe one day.’ Don’t ‘maybe one day’ it. Life is short, things happen. Do it now,” Sandra says.
