I own the HD-DVD and Blu-ray (just upgraded) versions of The Lake House and note that every single profile (all 39) for this film (except my HD-DVD) has his name wrong.

They all list him as:

Tomas Voth [Tomãs Voth]

His name doesn't have a tilde '~' over the 'a' but actually has a straight bar.  This is very obvious in high definition.

I've learned this is a Macron (http://en.wikipedia.org/wiki/Macron) and the character is a Unicode character we can't represent in the database yet so it should be entered using the normal ASCII characters (Rade Serbedzija anyone).

So this is an FYI for anyone with The Lake House.  I've already submitted the change for my Blu-ray profile.
