After watching Gravity, you will come away with two strong impressions.

The first is that it is perhaps the most engrossing space movie you have ever seen.

The second is that leading lady Sandra Bullock is a fox.

At 49 years of age - yes, 49! - the US actress looks better than ever in Gravity, which opens here on Oct 10.

She plays Dr Ryan Stone, a scientist who is doing a space walk when all of a sudden, her shuttle is destroyed by some errant debris.

She finally manages to scramble aboard a nearby Russian space station, which is exciting, and then things get even more exciting when she strips off her space suit.

Now THAT is a heavenly body.

Anyway, can her fellow astronaut, played by George Clooney, save her pretty behind?

We certainly hope so. She's too hot to die!

Of course, Bullock isn't the only half-centurian to maintain her awesome physique.

These days, 50 is the new 35, and veteran ogler Jason Johnson has the goods on some choice older gals who have managed to defy both time and gravity.
