Summer 2011 is chugging ahead full steam and that means plenty of TV spots teasing some of the most hotly-anticipated films that’ll hit theaters this year. This includes J.J. Abrams’ latest sci-fi project, Super 8, and the epic finale, Harry Potter and the Deathly Hallows: Part 2.

Like the most recent Super 8 TV spot, the latest pair of small screen previews released for Abrams’ new project do away with the whimsical Cocoon musical score and wondrous atmosphere of the original Super 8 trailer – and instead focus on the more mysterious monster movie genre aspects of the film.

Abrams provided little in the way of concrete information about Super 8 in the past, saying:

“To me, all people need to know is that it’s an adventure about a small town and it’s funny, it’s sweet, it’s scary and there’s a mystery: What is this thing that has escaped? What are the ramifications of its presence? And what is the effect on people?”

Paramount has decided to downplay the “funny and sweet” side of Super 8 in these television clips, which make the film look more like a 1970s-set supernatural horror flick (not in a bad way, mind you) than anything else.

Super 8 may be largely an homage to Amblin sci-fi flicks of the 1970s and 80s like E.T., but we seem to often forget just how eerie and sinister those film are at times. Those movies are dead serious when it comes to building atmosphere and anticipation for the reveal of the mysterious, possibly dangerous other-worldly creatures that have arrived on our planet.

Case in point: Check out this abduction scene from Close Encounters of the Third Kind (and note the parallels to the Super 8 footage) below:

Harry Potter and the Deathly Hallows: Part 2

What else is there to say about the Warner Bros. teenage wizard saga at this point? Over the course of a decade, we’ve watched franchise stars Daniel Radcliffe, Emma Watson and Rupert Grint go from being the little kids battling magical creatures (and schoolyard bullies) in Chris Colombus’ original Harry Potter movie – to now, young adults engaged in a full-out war against the Dark Lord Voldemort (Ralph Fiennes) and his forces in director David Yates’ undeniably epic conclusion to the franchise.

The Deathly Hallows: Part 2 trailer teased quite the action-packed roller coaster ride of a finale, and the first TV spot released for the film very much does the same. We’ve still got two months until what is arguably the most anticipated movie of the summer hits theaters, so expect to see plenty of more Harry Potter-related marketing paraphernalia over the upcoming weeks as well.

In the meantime, check out the first Harry Potter and the Deathly Hallows: Part 2 TV spot below:

Super 8 hits theaters next month on June 10th.

Harry Potter and the Deathly Hallows: Part 2 arrives in theaters just over a month later on July 15th.
