What movie has the line "The party has just begun" in it? It's from
some early 1970's American movie about a convict on the loose. What is
the title of the movie that has the above dialogue in it?

Hi overijse,

The only reference I was able to locate to the line ?The party has
just begun? is described below:

"On August 23rd, 1973 two machine-gun carrying criminals entered a
bank in Stockholm, Sweden. Blasting their guns, one prison escapee
named Jan-Erik Olsson announced to the terrified bank employees ?The
party has just begun!? The two bank robbers held four hostages, three
women and one man, for the next 131 hours."
(...)
"...The hostages had begun to feel the captors were actually
protecting them from the police. One woman later became engaged to one
of the criminals and another developed a legal defense fund to aid in
their criminal defense fees. Clearly, the hostages had ?bonded?
emotionally with their captors.
While the psychological condition in hostage situations became known
as ?Stockholm Syndrome? due to the publicity ? the emotional ?bonding?
with captors was a familiar story in psychology."
