Stephen Amell in his new Green Arrow costume The CW

It looks like the Arrow season 4 trailer is just around the corner. With the popular superhero series set to return in October with its new season, fans are hoping to catch a glimpse of the revamped version of Arrow in action.

After three seasons, lead character Oliver Queen is finally embracing his comic book roots and becoming Green Arrow. While his updated look/costume has already been revealed, it will be interesting to see how actor Stephen Amell plays out his new and slightly different superhero identity. Earlier rumours have suggested that season 4 will feature a more light-hearted, witty and fun version of (Green) Arrow as compared to what we have seen so far.

Arrow showrunner Marc Guggenheim posted the following tweet teasing the upcoming trailer:

The show's executive producer Wendy Mericle recently teased on Twitter that the Arrow season 4 trailer is going to break the Internet.

So what can fans expect from the first trailer of season 4? "Perhaps the trailer will reveal what force will draw Arrow back to Star City after his extended sabbatical with Felicity Smoak... or finally say the words - 'Green Arrow?'" speculates a ComicBook report.

Hopefully, we will also get to see season 4's main villain - Damien Darhk (played by Neal McDonough) and John Diggle in costume. Based on Guggenheim's tweet, and with Arrow season 4 set to premiere on 7 October, 2015 on The CW, expect the trailer to release online anytime around the first week of September.
