This actually looks pretty good. At first glance the trailer almost looked like Catch Me If You Can 2. Which I'm guessing it probably will feel like, maybe with dashes of Moulin Rouge. Why Moulin Rouge? Think about what we see in the trailer:

Ewan McGregor
Ewan McGregor talking about love
Ewan McGregor tapping at a typewriter about love
Ewan McGregor falling in love
A woman who doesn't believe in love
A woman who falls in love anyway...

Sound familiar? This looks to be the one romantic comedy I'll see this year.
