Will - who works as a correspondent for ABC News - was invited to play a small role in the new superhero film 46 years after his dad first donned the cape to play the Man of Steel and the 32-year-old reporter admitted he was more worried about delivering his one line than any of his previous TV gigs.

He told TMZ.com: "I know the folks making the film, and they’ve been so kind to me and my family, and I had a free day, so we made it [happen].

"I don’t know what I’m allowed to say. It was a really great experience; they were super friendly; it was quick, easy …

"I was actually more nervous doing that than I am whenever I’m on TV for my normal job because there was so many people around and I had to memorise one line, but still!"

No further details are known about Will's cameo but rumours suggest he will be playing a TV reporter. Christopher Reeve played Superman in four films and also made a cameo appearance in spin-off TV series 'Smallville'. He died in 2004 almost a decade after he was paralysed in a horse-riding accident.

Writer/director James Gunn recently admitted his new 'Superman' movie is "getting close" to being finished following a six week shoot in Cleveland, Ohio.

He clarified on Threads: "We are not done shooting. Still a couple weeks left. Just done shooting in Cleveland.

"And yeah it's a long shoot ... but we're getting close!!"

The film stars David Corenswet as Superman/Clark Kent, while Rachel Brosnahan has been cast as Lois Lane, and Nicholas Hoult will play Lex Luther.

Gunn expressed his gratitude for the city of Cleveland, hailing it a "special place".

He wrote: "Cleveland – today we are leaving you after six amazing weeks of shooting. From the moment we first came here on a scout a tad less than a year ago and Terminal Tower was lit up with the colours of Superman, I knew you were a special place.

"I would walk down your streets and someone would stop me and tell me how grateful they were we were shooting in their city – not once, not twice, but dozens of times.”

He also heaped praise on the "wonderful background actors" for helping remind him why he loves making moves. He continued: "The wonderful background actors on the film were always so fun and funny and they clapped after takes, something that reminded us Hollywood cynics why we make movies in the first place.

"The pride you feel in being where Jerry and Joey first created Superman was invigorating. You exemplify his spirit.

"But just as much it's the pride you have in your community, your hometown, your radio stations and restaurants and gatherine places that touched me. "Every city would be so lucky to have people that loved their city as much as you. You simply couldn't have been more wonderful, kind, or accomdating to me and our performers and crew."
