Actor Ethan Hawke has teased that director Richard Linklater's "Before" trilogy can become a quadrilogy.
The actor, 46, who has starred in all three films with Julie Delpy, hinted at the possibility of another installment, but it will be a while before a decision is made, reported The Independent.
"I would have said after the second there was definitely going to be a third one, but I do feel complete in that the first one starts with the older couple arguing on the train, and by the end of the third one, we've become that couple.
"If it were to continue, it would change shape. It would be something else," Hawke said about the journey from 1995's "Before Sunrise" to 2013's "Before Midnight".
Linklater told Entertainment Weekly in an interview earlier, "No one's ruling out a quadrilogy or sextology or whatever. We just don't know.
