For me it is "**Casablanca (1942)**". Why?  It's a romance film, packed with a great story, great characters, and some of the greatest lines ever uttered in cinema. &gt;*Famous Lines* -   "I think this is the beginning of a beautiful friendship. "  "Of all the gin joints, in all the towns, in all the world, she walks into mine""  "**Kiss me as if it were the last time.**"
