Actress Zoe Saldana says Vin Diesel's Groot "stole the show" in their latest offering "Guardians of the Galaxy".

The 35-year-old says she "fell in love" with the tree-like creature in the new Marvel movie - in which she plays Gamora and can't remember feeling "moved" as much by any other fictional character, reports contactmusic.com.

She said: "I think Groot stole the show, for me. I mean, I just fell in love with this big tree once we started filming. And even though I'm mature and I'm pretty sane, I can't really remember a fictional character that really moved me like that."
