Ryan Reynolds and Emma Stone
Ryan and Emma might be two of Hollywood's most gorgeous actors, but in The Croods they only lend their expert voiceover skills.
However, despite the film taking over two years to create, the pair only worked together a handful of times and often recorded their parts alone.
In an interview about the flick, Ryan said: '[We] worked together a couple of times, but we were often alone.
'You feel the chemistry, though, because you hear what everybody else laid down a few days before.'
