In 2001, she made a documentary about Pasolini, "Pier Paolo Pasolini e la ragione di un sogno." She also donated her papers related to their long friendship along with more than 1000 volumes and many documents connected to Pasolini to the archives of the "Fondazione Cineteca di Bologna", thus creating the "Centro Studi Archivio Pier Paolo Pasolini". This "Centro", strongly wanted by Betti, owns also thousands of photograph and all the works of Pasolini: poetry, literature, cinema and journalism. After her death in 2004 her brother "Sergio Trombetti" has donated all the personal documents of her career to the "Centro" that has absorbed them under the name "Fondo Laura Betti".
