It’s become a trend for studios to release new teasers and trailers skewed towards celebrating various holidays (last year’s Christmas “card” from The Babadook was particularly inspired). And while some of these promos aren’t so great, this new Ant-Man trailer from Marvel is a pretty nice Father’s Day gift.

We haven’t seen much of Scott Lang’s family life in the previous trailers, though they have briefly hinted at his relationship with his daughter. Actually, come to think of it, none of the trailers have shown us Judy Greer’s role in the film, either. But the latest promo shows off Greer’s part as Lang’s wife, and gives us more of a sense of Lang’s journey to becoming a better dad.

There’s also some new action footage, as well as another peek at that awesome toy train sequence, which looks like it could very well be the best scene in the film.

Armed with the astonishing ability to shrink in scale but increase in strength, master thief Scott Lang (Rudd) must embrace his inner-hero and help his mentor, Dr. Hank Pym (Douglas), protect the secret behind his spectacular Ant-Man suit from a new generation of towering threats. Against seemingly insurmountable obstacles, Pym and Lang must plan and pull off a heist that will save the world.

Ant-Man also stars Paul Rudd, Michael Douglas, Corey Stoll, Bobby Cannavale and Evangeline Lilly, and hits theaters on July 17.
