The Invasions show is planned for later this month at the Foyle Arena.
Councillor Cooper said:
“At the committee this week details were released about the Invasions/Heroes and Legends Show which will held in the Foyle Arena on Saturday 28th and Sunday 29th October.
“From Sinn Feins perspective the pricing model of £9.50 per adult and £35 for a family ticket would have proved unaffordable for many lower income families.
“This led to me proposing that the pricing structure be revisited to see what options were available to make it more accessible.
“As a direct result the company who will deliver the event have agreed with council to raise the free admission age barrier from 3 years old to 5 years old.
“Given the nature of the event and the characters who will be appearing, I am confident that this will allow many more families with young children to be able to afford to attend.
“The company have also agreed to run multiple competitions for family tickets online and on Saturday October 22nd there will be a free meet and greet with key performers from the show, Bumble bee, Optimus Prime and others – this will be open to all and held in the Guildhall’s Main Hall which can meet up to 1000 people.
“This will be free of charge and should make the event accessible.
“I would like to express my gratitude to the company and the council officers involved for their work in bringing these new proposals forward.
“I look forward to a massive level of interest in both this event and all the council events being held this Hallowe’en,” added Cllr Cooper.
