Oh no there's too many to choose from it's too hard.
I'll have a very thorough think about it.
Well the actress would be Scarlett Johansson, that one's quite easy. But I'm not sure about the actor there's too many I like. Recently my favourite actors have been Christian Bale, Leonardo DiCaprio and Ewan McGregor (in addition to my other favourites) but I'm just not sure because I love Orlando Bloom too (more for his looks though, although this isn't about acting skills anyway). Ermm I think I'll choose Leonardo please. But this will probably change.
Johnny Depp, because he could totally pull a Jack Sparrow and get us out of there. And he seems like a cool guy that I at least, could tolerate possibly spending the rest of my life on an island with.
And Ellen DeGeneres. Because she'd always keep us entertained. She seems like a really nice person to talk to as well. And I'd have no competition for Johnny.😛
