Amber Heard ''raises her game'' when working with ''great talents''.

The 29-year-old actress feels ''very lucky'' to have starred alongside Eddie Redmayne in 'The Danish Girl', Christopher Walken in 'When I Live My Life Over Again' and James Franco in 'The Adderall Diaries', because they are all so talented, which inspires her to push herself harder.

She said: ''I'm very lucky that I've been able to work with actors like Eddie Redmayne, Christopher Walken and James Franco.

''When you find yourself among great talents like that you experience a tremendous sense of satisfaction. It helps you raise your game as well.''

In 'The Danish Girl', Eddie plays Lili Elbe, one of the first people to have gender reassignment surgery and Amber thinks it will do a lot to educate people and break down taboos around the subject.

She told HELLO! magazine: ''It's an issue that is gaining more and more attention and it's going to help the transgender community deal with the social and sexual stigma attached to gender issues.

''Gender identity was not a big issue in Greek and Roman times, where notions of gay or straight were not so rigidly defined as now.

''A film like this can break down a lot of taboos and misconceptions - and Eddie gives an incredible performance.''
