Neil was conceived off the back of a one night stand between Nessa and Smithy amid their tumultuous relationship.
Oscar made his first appearance in the finale of series two in 2008 and was last seen in the festive special in 2019.
At the screening he looked stylish in a red star-patterned cardigan, white T-shirt and baggy jeans.

Aside from his Gavin And Stacey hustle, Oscar has since turned his attentions to music and is the guitarist and co-frontman of South Wales band Redwood City.
Last year the young musician even competed on The Voice Kids as a solo artist.
Reflecting on his acting past, Oscar has previously told The Sun: ‘I grew up knowing I was Neil The Baby, but it was after the Christmas special (when he was 10) that my life literally turned around.
‘I went from a kid that was in a show when he was a baby to a kid in a TV – even going into the supermarket was mad.’
The critically acclaimed series follows the lives of titular characters Gavin from Essex and Stacey from South Wales, documenting key points in their long-distance relationship and events that bring the two families together.
Gavin and Stacey fist aired on BBC Three in 2007 and spanned 20 episodes over the course of three series.
As well as James and Ruth, it turned Mathew Horne and Joanna Page into household names.
The supposed ‘last ever’ installment will air in a 90-minute special on Christmas Day this year after fans of the show begged for an end to the story.

It comes after James and Ruth revealed Gavin & Stacey fans will be treated to a lot more Smithy and Nessa in the final episode, musing that their characters’ ‘messy’ relationship is the beating heart of the BBC show.
Appearing on the podcast Table Manners with Jessie and Lennie Ware, the actors and writing partners teased the Christmas special, spilling that fans will find out a lot more about Ruth’s character Nessa’s past as well as her future with Smithy.
‘Nessa has had this unbelievable checkered life and you find out more about that in this special — some really fun bits that we wrote,’ James explained.
He mused that the reason fans have taken Smithy and Nessa to their hearts is because ‘on TV or films, you very rarely see people that look like Ruth and I fall in love.’
‘You just don’t. I’d be dropping off a TV to Hugh Grant in Bridget Jones and Ruth’s like working on a newsstand when someone buys a newspaper.’
‘What I like about the show is that it’s so messy and complicated and they just clearly have fantastic sex. I really enjoy that confidence.’

Ruth added though that in the early days, the writers partners were unsure how to pitch the unique relationship, explaining: ‘The first time they had sex was in the very first episode and I think because we didn’t quite know what the show was we were probably being quite sitcom about it.’
‘We were there, just the two of us, on that road that had meant so much to us and I just, as Ruth, was looking at my dear friend James and when I said ‘I loved you with all my heart’ I was saying it to you [James],’ Ruth recalled.
Despite the pair now promising the upcoming special actually is the finale, there’s been a flurry of fan speculation that there could be more to come.
James is adamant though that this is it, giving an ominous warning to viewers as she said: ‘It can’t carry on. When you’ll see it, you’ll know.’
