'Mirror Mirror': Julia Roberts' Evil Queen Gets Angry With Armie Hammer's Prince (VIDEO)

How manipulative is Julia Roberts' Evil Queen in "Mirror Mirror"? If this new clip from the upcoming film is any indication, very manipulative!

In "Mirror Mirror," Roberts plays a mean enchantress attempting to defeat Snow White (Lily Collins) and take control of her realm. In the meantime, she tries to woo the charming Prince Andrew Alcott (Armie Hammer). However, things get complicated when the Queen discovers the Prince is attracted to her enemy.

As you can see in the video above, this bit of information does not sit well with Roberts. (Also, something else you can learn from this clip: Eating dinner with the Evil Queen is not a pleasant experience.)

You can see more of Roberts' sass when the Snow White adaptation "Mirror Mirror," starring Collins, Hammer and Nathan Lane, hits theaters on March 30.
