Many fans were hoping that the first Aquaman trailer would premiere this weekend at WonderCon, and there were even some bogus rumors floating around about it, but the Warner Bros. panel came and went without a trailer.

Aquaman director James Wan must have saw some of the fan reactions because he took to Twitter to set the record straight. Check out his reasons for holding back the trailer below:

Hey friends, I usually do my best to avoid internet noises (especially fabricated distractions) but a teaser-trailer going out this weekend was never in the books — despite what some claim. It’s not because of anyone or any nefarious reason holding it back — IT’S ME. (1/3) — James Wan (@creepypuppet) March 25, 2018

I am simply not ready yet to share. This movie is filled to the gills with VFX, and the process is as slow and laborious as a sea-slug! Yes, even shots for the trailers take forever to do, and I refuse to put out anything that might be construed as subpar. (2/3) — James Wan (@creepypuppet) March 25, 2018

I know it seems like nothing much is brewing above the surface, but I can assure you, we’re working nonstop under the waves 🌊 😉 (3/3)

That makes sense to me! When you have a movie with the amount of visual effects an Aquaman movie would need, the wait for a trailer is going to be longer than something like a Batman movie that doesn’t have as much CGI.

Wan didn’t give any kind of hints as to when the first Aquaman trailer would drop, but my guess would be in a month or so. I’d assume Warner Bros. would want it ready to play in front of Avengers: Infinity War.

When do you think the first Aquaman trailer will drop? Next month? Or perhaps not until later this summer at San Diego Comic-Con? Let me know in the comments below.
