What if there was a library which held every book? Not every book on sale, or every important book, or even every book in English, but simply every book - a key part of our planet's cultural legacy.

I try not to go down the 'what if' road very often. It isn't fruitful and just makes you feel crummy.

I am in a traditional financial services business - but we at Fidelity can see that the evolution of technology is setting our industry up for disruption. What if this technology could do for the transfer of value what the Internet did for the transfer of information?

If Joy Behar or Sherri Shepherd was a dude, they'd be off TV. They're not funny enough for dudes. What if Roseanne Barr was a dude? Think we'd know who she was?

I ended up going to NYU for film school - close to Pennsylvania - but we talked about what if I went to UCLA or USC, and my mom's whole world was caving in.

What if God's a woman? Not only am I going to hell - I'll never know why!

My father wasn't perfect. He had a temper. I took some of that. He would snap, but the older he got, he started calming down. He learned about life, but the thing that he taught my whole family was that family was the most important thing and, no matter what, if a family member needs you, you go and help them out; you get there.

I want to be a Bond girl. Think about it - I have metal components in my legs, so when I go through airport security, I set off the alarms. But when they realize why I'm beeping, they let me through. What if I had weapons in my legs? I could take one off and pull out an Uzi! Legs Galore - that would be me!

It's been a very strong force for me over the years. I don't know exactly why. For some people, fear can be a very useful thing. They can use it to recognise there's something missing, and heal themselves. But fear can also destroy some people. I think I'm the first type of person. I'm pretty anxious, always thinking 'what if?' about the bad stuff.

I don't know how I didn't kill any one of my sisters. For this one horror film we were making, I made my own harness for my sister. I wrapped her in all these ropes, but then also put a noose around her neck and hung her from a tree. Now I think, 'What if my harness didn't work?' I'm so lucky that nothing ever happened.
