Diaz: I'm surprised by sequels
Cameron Diaz has admitted that she's sometimes surprised by the thirst for sequels.
The actress voices Princess Fiona in the animated franchise Shrek, which is now on its fourth instalment - Shrek Forever After.
"Often you do go 'Wow, really? That again? Didn't we already see that movie?'" Cameron said.
She went on: "But it just goes with beloved characters. People are often coming up to me, asking is there going to be another Shrek, is there going to be another Charlie's Angels?"
Shrek Forever After made 200 million dollars at the US box office.
