Rebecca Hall or Scarlett Jo? Also who do you think is better?

Scarlett Johansson and Scarlett Johansson

I am pretty sure your wrong on both. Does anyone else have input?

I don't know for sure, but I think that Scarlett Jo has more screen time, though I much prefer the acting of Rebecca Hall. She played her part brilliantly.

Scarlett Johansson has more screen time, Rebecca Hall delivers a much stronger performance.
