Richard Linklater is open to making a 'Boyhood' sequel.

The director of the critically-acclaimed drama film starring Ellar Coltrane, Patricia Arquette and Ethan Hawke has confirmed a sequel could be made, although he insisted it would not take 12 years to shoot like its predecessor.

Asked if a sequel could be on the cards, Linklater replied: ''To be honest, this film first met its audience exactly a year ago and for the first six months of the year, my answer to that was absolutely not.

''This was 12 years, it was first grade through 12th grade; it was about getting out of high school. I had no idea about another story, there's nothing to say. It hadn't crossed my mind.

''But I don't know if it's been a combination of finally feeling that this is over or being asked a similar question a bunch over the last year, that I thought, well, I wake up in the morning thinking, 'the 20s are pretty formative, you know?'

''That's where you really become who you're going to be. It's one thing to grow up and go to college, but it's another thing to... So, I will admit my mind has drifted towards [this sequel idea].''

However, Linklater said that the film would not take as long to make as 'Boyhood'.

He told the Q&A Podcast: ''The 12 years [structure] came out of [school structure]. It wouldn't have to be twelve years. It wouldn't have to be... I mean, who knows? I mean, if I learned anything on the Before trilogy it took five years to realise that Jesse and Celine were still alive and had anything to say. This one would probably be more accelerated, but who knows.''
