VENICE, ITALY (REUTERS) - Fans went wild for Hollywood star Jennifer Lawrence as she appeared on the red carpet in Venice for the world premiere of her real-life partner Darren Aronofsky's movie Mother!.

Fans had camped outside the red carpet overnight to make sure they would be well-positioned to catch a glimpse of the 27-year-old Academy Award winner.

In the film, Lawrence plays Mother, a young wife who lives with her poet husband - Javier Bardem - in a secluded country house. While he is trying to overcome a serious bout of writer's block, she is busy restoring his family home.

Their seemingly idyllic existence starts falling apart when unexpected guests - starting with Ed Harris and Michelle Pfeiffer - arrive at their doorstep.

Mother! is one of 21 US and international movies vying for the Golden Lion which will be awarded on Sept 9.
