Billy Crystal is going to help build the Sept. 11 memorial.
The 60-year-old actor was named Thursday to the board of directors of the National September 11 Memorial & Museum, the foundation raising money to build the memorial to the 2001 terrorist attacks.
Crystal becomes the 45th member of the board, joining "Analyze This" co-star Robert De Niro.
He participated in a benefit concert for the city a month after the terror attacks. He also has co-hosted eight Comic Relief telethons on HBO to raise money for the homeless.
The foundation has raised more than $350 million privately to build the memorial.
