Actor / Actress that you thought would hit the next level, but didn't

[nick604]

I always thought Anna Paquin was going to become a huge name, especially after her performance in A walk on the moon. She was solid in Buffalo Soldiers, and is a passable Rogue in the X-Men series (tho the directors seem to use her less and less as as each new film comes along), but can't say she's ever really delivered in the way I thought she was going to.
