New York, May 18 (Inditop.com) Hollywood actor Sean Penn will miss the premiere of his new film “Fair Game” at the ongoing 63rd Cannes International Film Festival to testify at a US Senate committee about the mess in Haiti, says his publicist.

The Oscar winner is instrumental in ensuring many of the devastated nation’s people receive aid following the earthquake, which killed hundreds of thousands of citizens in January, reports nypost.com.

He will give evidence to a Senate committee in Washington later this week to detail the destruction he witnessed in the country – leaving him unable to make Cannes for the glamorous premiere of his new movie.

In “Fair Game”, he plays the husband of CIA agent Valerie Plame (Naomi Watts).
