"Glimpsing remnants of the fake blood - he quietly caved in.
Swiftly broken, let the facade fall."
"That poem's about my baby brother Paul, who played our uncle Jackie in the film 'Sunday'.
"Paul obviously wasn't an actor, he just wanted to do his best for the family, and it took more out of him than anyone would ever know.
"It was true that there was dried-in fake blood on his collar, and he absolutely crumbled when I pointed it out, and that's where the poem came from."
Julieann Campbell's uncle, Jackie Duddy, was the first person to die on Bloody Sunday.
She and her brothers never knew their uncle, but he has always been a major part of their lives.
A poet, Julieann has written widely about Bloody Sunday, including 'Pablo's Part', about her brother Paul's role in the film.
She is the co-editor of a collection of poetry about the day, and is on the board of the Bloody Sunday Trust.
"It has dominated the lives of people in my family, and my poetry is possibly the only way I have to express what's been filtered down to us through the generations.
"We weren't brought up political but we were all very artistic in our house, so that was my way of doing things.
"My brother Paul, for instance, as well as being in the film he writes songs, and he's written a lot of songs about Bloody Sunday.
"When they first offered him the role of my uncle Jackie he had to consult the family and he had to ask our Mum in case it was opening up raw wounds.
"Since we were young my Mammy always worried they were going to make a film about Bloody Sunday, and strangely enough they did and her son played her dead brother."
Many of the family, including Julieann herself, are in the film.
"It was definitely a sensitive time, but the whole family was behind us as long as we did it right, and they'd rather we did it than someone else.
"It was the hardest work we ever did, but we did it right.
"It's very strange that he'd had such an influence on our lives given that we've never met him.
"My mother's always talked about him, he was her best brother growing up, her sparring partner as she calls him.
"He's always been important, never forgotten, and just mentioned in everyday conversation.
"So he's always just been accepted as always being there, and it doesn't really matter that we didn't meet him, we love him anyway."
One day, Julieann will tell her six-month old daughter, Saffron, about her great-uncle.
"I'll probably tell her the same as my Mum told us, that he went out marching for a bit of craic and got killed.
"That was the way it was put to us children when we were young.
"We knew something happened but we didn't know really what, we just knew Bloody Sunday."
