The perils of competing for attention at Cannes! Eva Longoria struggles with her dress' long, heavy train

With the crème de la crème of the celebrity world expected to make appearances at this year's Cannes Film Festival, the pressure is on to stand out from the crowd.
So it's no wonder that Eva Longoria chose a stunning gown with a long train for the screening of Moonrise Kingdom by Wes Anderson last night.
However, Eva was perhaps a little too concerned about making an impact to worry about how she would manage in the gown on the red carpet.

Watch highlights of the Cannes red carpet below

The perils of looking glamorous: Eva Longoria wowed in a Marchesa gown on the red carpet at the Cannes Film Festival last night, but the long train of the dress proved problematic

The Desperate Housewives star was seen attempting to swing the silver dress, which featured a long train made of tulle, around her as she angled herself into the best positions for the waiting photographers.
And while she had an assistant on hand to help her at points during the photocall, Eva also had to rely solely on her own talents to ensure she didn't trip over the beautiful Marchesa gown.

Careful! While Eva had an assistant on hand to help her at points with the dress, she also had to manage it herself

Standing out from the crowd: Eva certainly caused a stir in the beautiful dress

The main body of her dress featured intricate silver and diamante details, and a transparent cutaway section on the back.
After making her way inside into the movie premiere, Eva wrote on Twitter: 'Just climbed the mythical Red Stairs of Cannes.Such a huge emotion, and what a fantastic Electric look!'
