The 70-year-old actor put a protective arm around his daughter as he gave the youngsters an access all areas visit of the future blockbuster's filming location.

The Behind The Candelabra star was wearing tweed trousers and a matching brown waistcoat over a pink shirt and red tie.

Meanwhile, his children looked excited to be on filmmaker Peyton Reed's set and were sporting VIP passes around their necks.

The Hollywood A-lister's grey goatee gave him an air of wisdom to play the original Ant-Man, who mentors Paul Rudd's central character, Scott Lang.

The plot will see Michael's character hire a reformed thief and electronics expert (Rudd) to look after his size-altering technology.

But when things go wrong, Lang is transformed into Ant-Man, who makes it his mission to defend humanity from evil.

The cast also includes LOST alumni Evangeline Lilly as Pym's daughter, Hope Van Dynem, while Corey Stoll takes on a star turn as villainous Darren Cross.

Michael - who is giving his marriage to Catherine Zeta-Jones a second shot after a trial separation - is excited about joining the Marvel team.

He recently told Vulture: 'Marvel has got it down to a science, pretty much, and they've got kind of a phenomenal track record.

'I love this picture they did this summer, Guardians of the Galaxy. It's really good!

'I think that's given Marvel the confidence to step out in this whole new area, so I'm looking forward to adding to it.'

Ant-Man is scheduled for release on July 17, 2015.
