Movies like Love Actually and the Princess Bride?

My two favorite movies are Love Actually and the Princess Bride- can anyone recommend movies that are similar to these?

I suppose they're basically romances, so here are various films I've enjoyed:
The Truth About Cats & Dogs
How to Lose a Guy in 10 Days
The Matchmaker~Janeane Garofalo
Bridget Jones's Diary
While You Were Sleeping
Four Weddings and a Funeral
Angel (2007)
A Little Romance
Under the Tuscan Sun
My Brilliant Career
Eternal Sunshine of the Spotless Mind~sci fi romance
Pride & Prejudice~Keira Knightley version
Serendipity
Only You
Picnic
Home Fries~not a traditional romance by any means!
Swashbuckler~piratical romance and adventure with Robert Shaw and Genevieve Bujold
Romancing the Stone
Jewel of the Nile~sequel to film above but not as good
A Lot Like Love~love eventually
Father Goose
Houseboat
Pillow Talk
It Happened One Night
Three Coins in the Fountain
To Catch a Thief

Timely Romances:
Somewhere in Time~one of the most romantic films of all time!
The Love Letter (1998 TV movie)~This is a wonderful film about a man in the present day communicating with a woman in the past after he purchases a desk that used to belong to her.
I'll Never Forget You
Berkley Square
Time After Time~a bit more violence, but a great love story!
The Lake House
The Ghost & Mrs. Muir~not quite time travel

I ijust have to include these, even though they're sadder or even tragic:
Romeo & Juliet (1968)
Gone With the Wind
Forever Amber
Casablanca
Vertigo
Charade
Roman Holiday
Untamed Heart
Love Is a Many Splendored Thing

Musical Romance:
Gigi
Lili
My Fair Lady
Seven Brides for Seven Brothers
Singin' in the Rain
Funny Face
Daddy Long Legs
Grease
Grease 2

Sense and Sensability
The Importance of Being Earnest
