Drama reigned supreme at the amfAR Cinema Against AIDS Gala 2012 at the Cannes film festival on Wednesday night. Co-chaired by Alec Baldwin, the annual gala sponsored by the American Foundation for AIDS Research includes a live auction and runway show to benefit the charity.

Fashion-wise, the theme of Cannes' biggest night was drama, drama, drama as glammed-up celebs sashayed several bold dresses down the red carpet, including Jessie J's cutout red leopard Louis Heal dress, Kate Upton's navy peplum that seemed to be reproducing its way down her body in real time, and Kirsten Dunst's multi-layered Louis Vuitton confection. Diane Kruger and Joshua Jackson continued their Cannes takeover, with Kruger in beautiful white Chanel. Heidi Klum popped up in fringed silver Marchesa, and Milla Jovovich looked fittingly space-age in her structured gold Atelier Versace gown.

amfAR's event has raised more than $70 million for AIDS research since launching in Cannes in 1993. This year's gala included an all-black fashion show staged by Carine Roitfeld.
