In December 2009 Jude was in some broadway shows that just happened to be at the same time as Sienna Miller was on broadway. I'm not saying there's a connection there but they seemed to rekindle their relationship around that time. A couple years later though they announced they had split up again in February of 2011. I say at least they tried. That's more than most people do.
The first movie I saw Jude Law in that impressed me was Gattaca. If you havn't seen that movie I would recommend watching it. Other movies I really liked him in was Midnight in the Garden of Evil,eXistenZ,Enemy at the Gates(Ed Harris),A.I. Artificial Intelligence, Road to Perdition(Tom Hanks),Cold Mountain,The Holiday and Repo Men.
