Trailer Roundup: Watch these previews for 'Palo Alto,' 'Sex Tape,' 'The Drop' and more in case you missed them debuting this week!

This week provided us with some great new previews of upcoming films. They included the final James Gandolfini movie, The Drop, and even a gritty action film with Scarlett Johansson, Lucy. Let's take a look at these trailers and more below!

So James Franco wrote a book about an older man having an affair with an underage girl and got Gia Coppola to direct the film adaptation with Emma Roberts costarring opposite him. Then this week he hit on an underage teenager on Instagram, coinciding with the film's trailer being released. He's either super creepy or a great marketing strategist.

As most celebrities know, sex tapes are hard to hold onto. Though some are intentionally leaked, we suppose. So when a normal couple (played by Cameron Diaz and Jason Segel) decided to make one in the aptly titled new movie Sex Tape, things can only go wrong and get hilarious.

Are you ready for one last, overage ride? Sylvester Stallone's incredibly entertaining Expendables series is ending as a trilogy and this week we got to watch a great trailer for the final installment.  Though we loved the previous films, this new preview already makes the third movie look so much bigger than them. We should expect a lot more for this conclusion.

Luc Besson is an incredible filmmaker, responsible for some tough female protagonists (see: The Professional and La Femme Nikita). With Lucy, he teams up with Scarlett Johansson for "an action-thriller that tracks a woman accidentally caught in a dark deal who turns the tables on her captors and transforms into a merciless warrior evolved beyond human logic." Yes, please!

Here's the first trailer for Lucy!

James Gandolfini passed away last year with a number of projects yet to be released. One was a film called The Drop, costarring Tom Hardy, about two men that end up on the wrong side of a robbery. Could we ask for a better film for James' last performance?
