BBC 2 starts a new 6 part drama series on Tuesday 21st July called Desperate Romantics. It follows the young radical art movement as they rebelled against the established art world of Victorian London. The series may be more about their complex love lives than their paintings, but it's worth a look. Even if it's not your cup of tea, click on the link as the website has lots of information on the paintings featured, how they made the series and clips from each programme.
If you want to see some Pre-Raphaelite paintings in the flesh, the nearest place to visit is Birmingham Museum and Art Gallery, which has a good collection.
