Stranger Things' directing duo Ross & Matt Duffer have added three more castmembers to the highly-anticipated second season.

According to EW - Sean Astin joins the ensemble as RadioShack manager Bob Newby, who went to the same high school as Joyce (Winona Ryder) and Hopper (David Harbour).

It's no coincidence that the Duffers selected the 45-year-old Oscar nominee, who played Goonies leader Mikey Walsh in Richard Donner's 1985 treasure hunt classic.

Perhaps Bob will provide low-fi technology to the eighties gang of precocious tweens on bikes.

The Goonies famously featured DIY spy gadgets and booby traps as well as a gaggle of Oregon kids facing foreclosure.

Also new to Hawkins is Paul Reiser, who will play Department of Energy representative Dr. Owens 'tasked with containing the events of last year.'

It's sounds similar to the corporate villain the 59-year-old Golden Globe nominee played in James Cameron's 1986 sci-fi action masterpiece Aliens.  

'Very psyched to be joining great cast of @Stranger_Things!' the Mad About You alum tweeted.

Perhaps Dr. Owens will replace Hawkins Laboratory head Dr. Martin Brenner (Matthew Modine), whose character was attacked by the monster.
