Just a few weeks ago at Comic-Con, Warner Bros. unveiled the new trailer for Batman v Superman: Dawn of Justice, which fans have been poring over ever since. Youtuber Albert Lopez decided to give us a much different version, adding in the beloved It's Always Sunny in Philadelphia song "Dayman," while cutting together footage pitting "DayMan" (Superman) against the "NightMan" (Batman). We'll have to wait until next spring to see if DayMan can utilize his mastery of karate and friendship to defeat this NightMan.

Super Mario Bros. Honest Trailer

After a one-week hiatus following Comic-Con, Screen Junkies has delivered a new Honest Trailer, which pokes fun at the derided 1993 bomb Super Mario Bros., considered by many to be the worst video game adaptation of all time. The video offers a surprising comparison to Bob Hoskins' Eddie role in Who Framed Roger Rabbit?, plus plenty of other digs at the movie that caused Nintendo to stop licensing out their games for live-action movie adaptations. After watching this video, can you really blame them for taking that stance?

Iron Man Invades Los Santos in Grand Theft Auto V

Ever since Grand Theft Auto V was released a year and a half ago, fans have been creating fun mods that brings their favorite movie characters into the game. GameplayRJ has created a new mod where Tony Stark himself, Iron Man, lays waste to the streets of Los Santos with his arsenal of weapons. This isn't the heroic Stark we're used to in the MCU, but the weapons at his disposal seem quite accurate.

Marvel's The Avengers' Total Spoilage Animated Video

The fine folks at How It Should Have Ended have put together an animated video that offers a different look at the ending for Marvel's The Avengers. The video pokes fun at numerous aspects of the blockbuster, including Agent Coulson's (Clark Gregg) surprising resurrection on Marvel's Agents of S.H.I.E.L.D. and the bickering nature of Earth's Mightiest Heroes.

Real Fake History Tells Little Mac's Story From Mike Tyson's Punch Out

One thing I look forward to every Tuesday is a new episode of Real Fake History, and today the web series delves into a subject close to my heart, well, my childhood's heart anyway: the Nintendo video game Mike Tyson's Punch Out. We hear from Mac's trainer, Jerome "Doc" Louis, one of Mac's opponents, Soda Popinsky, and even from Mike Tyson's opponent in the game, Mac himself. Although it seems the barrage of punches he took has taken its toll on his mental state. Check back next Tuesday as the Real Fake History crew tackles Starship Troopers.

Game of Thrones' 8-bit Death Scenes

Throughout the first five seasons of Game of Thrones, the show has delivered countless memorable deaths, a tradition that will surely continue when Season 6 debuts next year. To help pass the time before the new season arrives, pipocaVFX has put together an entertaining 8-bit video that reenacts some of the show's iconic deaths, including Ned Stark's beheading, Renly Baratheon's death by "shadow," the Red Wedding and the bathroom murder of Tywin Lannister. There are even the two most shocking deaths from Season 5 in this fun video.

The Top 10 Most Beautiful Movies of All-Time

Cinefix has put together another top 10 list, where they break down their picks for the 10 most beautiful movies of all time. Classics such as 2001: A Space Odyssey, Manhattan and Lawrence of Arabia make the list, along with a few modern marvels like Hero and The Tree of Life. They also put together a "mini-montage" of more beautiful films that didn't quite crack their top 10 at the end of this 11-minute video.

Make Your Own Replica Hoverboard from Back to the Future Part II

Last month, Lexus unveiled their real, working hoverboard, inspired by the 1989 classic Back to the Future Part II. Unfortunately, that was only a prototype and won't be for sale, but if you still pine for the classic pink hoverboard, Dustin at DIY Prop Shop has you covered. This new 10-minute video shows how you can print designs for the board, which you can make out of either wood or foam, to create a very convincing replica hoverboard. The whole project cost just $33, so if you ever wanted a hoverboard on the cheap, this video is right up your alley.
