Day four of the Cannes Film Festival saw the weekend see as busy a schedule as the week, packed with new premieres and photo calls. The big film of the day was Gus Van Sant's mystery drama Sea of Trees, which stars Matthew McConaughey alongside Naomi Watts. The premiere event saw Diane Kruger turn out in a shimmery smokey blue gown to a happy crowd. 

Natalie Portman made her directorial debut as she shared A Tale of Love and Darkness, with the Cannes crowd. It is an adaptation of Israeli author Amos Oz's autobiography, and was well received. 

It continues to be the year of the woman at Cannes as stars such as Andie McDowell, Sienna Miller and Jane Fonda dominate the red carpet. Discover the days events in more detail via the gallery below...
