The I Am Sam actor, who was wed to the SWEPT AWAY star for four years in the mid 1980s, is said to be very keen to get a role in the film entitled MADONNA AND CHILD.
Although the pair's latest screen outing SHANGHAI SURPRISE was a critical flop, Penn thinks they would sizzle on screen together.
A source tells British tabloid The Sun, "Sean's very serious about a reunion with Madonna. The idea just came to him. He thinks the electricity between them on screen would be tremendous."
Madonna and Child is a tale of a middle-aged star who dreams of recapturing her success. If negations go ahead the pair could be filming together in early 2004.
