And if her alabaster skin, perfect make-up and peacock-blue gown weren't enough for you, take note of her not-even-close-to-being-boring ponytail.
Amy joined her co-stars Ben Affleck, Henry Cavill, Gal Gadot and Holly Hunter on the red carpet at the Odeon Leicester Square in London on Tuesday (22 March).
And along with Brit guests Ashley James, Ferne McCann and Katie Piper, Amy looked the picture of elegance – as always!
The Lois Lane actress chose a beautiful, thigh-split Antoni Berardi gown along with metallic platform heels and minimal jewellery. Her make-up was also pretty natural and the whole look combined to enhance her fair skin tones and red hair perfectly.
You could have also been mistaken as to think, 'ponytail, boring' about her hair, but shame on you, because there was nothing boring about this sexy little updo.
Amy's hair was created by celebrity stylist and Charles Worthington brand ambassador Ken O'Rourke who called it a, 'polished, high, '60s pony, inspired by the embellished hair seen at Celine and Prada.'
Here, Ken offers his tips on how to recreate Amy's look at home:
1. First, add mousse to damp hair, then blow-dry it smooth using a round, bristle brush.
2. When your hair is dry and straight (you can always use irons to help), brush your hair back into a sleek ponytail and secure it at the back of your head with a covered band.
3. Bind the base of your ponytail with Swarovski Crystals and secure with pins. We also love these pearl ponytail bands, £8, accessorize.com which give a similar, glamorous look to your pony.
Or how amazing is this sparkly Art Deco style hair pin which could also be secured to the base of your ponytail, £11.50, boots.com?
4. Finish your look with a glossing spray like Charles Worthington Shine Booster All Over Gloss Spray, £5.99, boots.com to tame flyaways and add a red carpet shine.
