Jon Hamm and girlfriend Anna Osceola take a casual walk in LA

The in-demand actor is preparing to take over Chevy Chase’s iconic Fletch role next Spring.

But Jon Hamm has been taking it easy during his COVID-enforced downtime, with the 49-year-old Mad Men star seen walking his dog with girlfriend Anna Osceola on Tuesday.

The thespian couple, both of whom appeared in the Mad Men series finale, went casual for the stroll. 

The Richard Jewell star paired blue trousers with sneakers and a warm jacket as he walked the couple’s pooch.

Meanwhile Law & Order True Crime actress Anna sported dark blue leggings and a T-shirt which read ‘I Stand With My Pack’.

Her flame-haired tresses were pulled back in a pony tail and both members of the couple wore aviator style shades. 

Meanwhile, Hamm has revealed that the Fletch reboot will begin filming in the spring.

The star of The Town will play the investigative reporter M. ‘Fletch’ Fletcher in a new adaptation of the 1985 comedy thriller that starred Chevy Chase in the lead role and has explained that he hopes to be filming in New York by early 2021.

Jon told Collider: ‘We’re hoping to start shooting in the springtime, in New York City – you know, fingers crossed. We’ve got an excellent script, and an excellent director attached, and we’re going to start casting soon. 

‘It’s big shoes to fill, obviously. But as I’ve mentioned in previous conversations, it’s a reboot, it’s not a remake, so we’re going back to the novels and really breaking it down but hopefully bringing what people want to see. 

‘So, fingers crossed!’ he concluded.

The new movie is being directed by Superbad filmmaker Greg Mottola and the plot is based on the second novel in Gregory McDonald’s book series, Confess, Fletch.
