James Marsden had to take on a DIY solution to keep his voice work going on The Boss Baby 2: Family Business after the COVID-19 pandemic shut down physical production.

The 48-year-old star takes over the role of Tim Templeton in the animated sequel, in which he and brother Ted (Alec Baldwin) must become children again to foil the evil plot of Jeff Goldblum's villainous headteacher Dr Erwin Armstrong.

Marsden told Yahoo Entertainment UK that his recording sessions were approximately 70% complete when COVID-19 forced the cast and crew into lockdown.

Along with his co-stars, Marsden received the necessary audio equipment from the production team and had to turn to DIY in order to ensure his setup was up to scratch.

He said: "I had to construct a home recording booth out of my kids' mattresses. Talk about going back to being a kid.

"When you're young and you create little forts out of sheets and blankets and things like that, I did that for real to create a home recording studio.

"It was like three or four mattresses. You create this sort of box and then throw blankets on top of it.

"It's you huddled in here with a little microphone and computer and you see [director] Tom McGrath on the screen. You're working from home doing voiceover work. I think some of it is in the movie that we recorded at home."

Marsden added that part of the enjoyment of making the film was "figuring out a way to still keep the engine running" when the pandemic got in the way of traditional methods.

Tom McGrath, who returned as director after helming the first movie in 2017, told Yahoo Entertainment UK that the film was one of the first Hollywood productions to get moving again in 2020.

He added: "I think the fact we had worked together closely in person allowed us to seamlessly work together at home.

"It was interesting in animation dailies and things because people's kids would want to watch. That was our test audience, to see if the kids were laughing at the animation."

The Boss Baby 2: Family Business is in UK cinemas now.
