Guardians of the Galaxy star Zoe Saldana has been announced as the 2015 Theatrical Fundraising Spokesperson for Brave Beginnings, a programme with the Will Rogers Motion Picture Pioneers Foundation, which gives grants to hospitals to improve the lives of premature babies.

Saldana stars in a PSA which will appear in US cinemas ahead of summer blockbusters, saying 'I want to talk about a different kind of hero. Instead of capes, they wear blankets. Every superhero needs a sidekick. I'd like you to fill that role by giving generously'.
