He is buried at Shalom Memorial Park in Arlington Heights . </P> <P> Upon Ramis's death, President Barack Obama released a statement, saying: "when we watched his movies--from Animal House and Caddyshack to Ghostbusters and Groundhog Day--we didn't just laugh until it hurt . We questioned authority . We identified with the outsider . We rooted for the underdog . And through it all, we never lost our faith in happy endings ." He ended his statement by saying he hoped Ramis "received total consciousness", in reference to a line from Caddyshack . </P> <P> Ramis and longtime collaborator Bill Murray had a falling out during the filming of Groundhog Day, which Ramis attributed to issues that Murray had with his own life at the time . They did not speak for more than 20 years . Shortly before Ramis's death, Murray, encouraged by his brother Brian Doyle Murray, visited him to make amends with a box of donuts and a police escort, according to Ramis's daughter Violet . At that point, Ramis had lost most of his ability to speak, so Murray did most of the talking over several hours . Murray gave tribute to Ramis at the 86th Academy Awards . </P>
