For the last ten years, Marisella has been responsible for the Lux Film Prize, the European Parliament award which was created in 2007. Strengthening ties between the cinema world and the members of the European Parliament, she became very experienced in managing contacts and activities with international film festival, European partners, film directors as well as with international institutions and organisations.

She chairs the Lux selection panel, in charge of choosing each year the ten films of the Lux Official Selection. She also coordinates the 28 Times Cinema project, a collaboration with the Venice Days sidebar of the Venice film festival and Europa Cinemas, and she has been in several short and feature film juries.
