Interstellar and The Dark Knight trilogy director Christopher Nolan, who's been instrumental in reviving DC and Warner Bros' superhero films, recently dissed all Marvel movies through a single remark.

Nolan's dismissive opinion of Marvel movies was indirectly revealed by Zack Snyder, director of Man of Steel and the upcoming Batman v Superman, in an in-depth profile of Nolan by The Guardian.

Apparently Snyder asked Nolan, who served as the Executive Producer on Man of Steel, for his opinion when the studio asked him to include a post-credit sequence in the style that Marvel's movies are known for.

Nolan replied: "A real movie wouldn't do that."

The 'serious' and 'dark' tone of DC films is a key aspect that separates their treatment from the comical and relatively light-hearted Marvel movies. Besides, including a post-credits scene is something that Marvel started and following that style would just show lack of originality on DC's part. So, perhaps Nolan's decision is right.

But with DC announcing a lineup of interconnected superhero movies including The Justice League films, it remains to be seen whether the makers will stick to their no-post-credit-scene policy or give in to popular demand.
