Actor Michael Douglas was seen on the set of Ant-Man today, looking dapper as the scientist Hank Pym, who develops the technology that creates Ant-Man.

While Marvel’s Ant-Man had a bit of a bumpy start, it seems production is going well, as today we have our first look at Michael Douglas as Hank Pym.

Pym is a biochemist, who discovers an unusual set of subatomic particles he would label “Pym particles.” Entrapping these within two separate serums using magnetic fields, Hank creates a size-altering formula and a reversal formula and tests the size-altering formula on himself.

He would then discover that the serum was more powerful than he had expected, and is reduced to the size of an insect in the original comic. But in the film’s storyline, he doesn’t get turned into Ant-Man, he develops the formula and Scott Lang (played by Paul Rudd) will turn be the one turning into Ant-Man.

After director Peyton Reed took over to helm the troubled film, there haven’t been many changes, but we recently saw Homeland actor Martin Donovan join the cast in a “pivotal role” despite being in the middle of filming.

It was back in August when we got our first look at Paul Rudd as Ant-Man, which revealed a much darker tone than we originally anticipated. In case fans missed the first image from Ant-Man, be sure to check it out.

Rudd’s character is an ex-con and thief who ends up finding a mentor in Dr. Hank Pym, who is played by Michael Douglas, a genius inventor of technology that allows him to shrink down to the size of an insect and increases the person’s strength.

We look forward to seeing more of Ant-Man as it continues production, which began in August, and let us know what you think about our first look at Michael Douglas as one of the film’s central characters.

Ant-Man will hit theaters July 17, 2015.
