What are your favorite book to film adaptations?

What do you consider some of the best book to film adaptations?

Mine are:

• Harry Potter and the Deathly Hallows: Part 1 (2010) & Harry Potter and the Deathly Hallows: Part 2 (2011)
• The Green Mile (1999)
• The Bourne Identity (2002)
• The Shawshank Redemption (1994)
• Jurassic Park (1993)
• The Great Gatsby (2013)
• The Girl with the Dragon Tattoo (2011) & The Girl with the Dragon Tattoo (2009)

I'm a fan of Nick Hornby's written work and I feel like the movies adapted from his novels are very enjoyable. For example:

• High Fidelity
• About a Boy (2002)
• Fever Pitch
• A Long Way Down

Oh man, I totally forgot to include The Godfather (1972) to my list.
