Who is the Queen of Ireland? Well apparently it is Dublin drag queen Panti Bliss.

Panti Bliss - aka Rory O'Neill - rose to international fame after her speech at the Abbey Threatre on gay rights went viral earlier this year.

Then she took on a central role in the marriage equality referendum, calling for a Yes vote.

And after the amendment passed, she declared: "I think this sort of says to the international community that, look, Ireland changed long ago and the vote today is confirmation of that change".

Now a new documentary follows Panti's journey from the small Mayo town of Ballinrobe, to striding the world stage.

"The film takes us behind the scenes with his alter ego Panti in the year she became the symbol of Ireland's march towards marriage equality," says Universal Pictures Ireland.

Directed by Conor Horgan and produced by Blinder Films, the film builds up a multi-faceted picture of a complex and compelling character "through behind the scenes footage and interviews with friends, peers and protégés".

These include Colm O'Gorman, Shirley Temple Bar, Una Mullally and Senator David Norris.

It will be in cinemas October 21st.
