I do really love 'Love, Actually" (as you may guess from the picture). I love Christmas so this movie fits into that category, but the whole cast is just brilliant.
Thanks for posting that. It had been driving me crazy trying to work out where I had seen Rick from The Walking Dead before (though not enough to actually get around to looking him up on IMDB).
Being a... ahem...more 'mature' woman, I fell in love with Last Chance Harvey.' Dustin Hoffman plays a lovely gentle soul who finds love later in life with Emma Thompson. It's cute and awkward and realistic.
It's hard to pick just one. I think for me it's maybe a toss up between Crazy Stupid Love (with Ryan Gosling and Emma Stone, mainly for THAT SCENE) an the Aussie flick Love and Other Catastrophes (Radha Mitchell, Frances O'Connor and a bunch of other talented people). I tend to prefer a bit of comedy in my romance. Oh, and there's One for the Money by Janet Evanovitch which has a blend of action and comedy.
