Fox Logo variant for Fantastic Four (2015)
Did you catch it? As the screen starts to fade on the 20th Century logo, the “F” stays on screen a few seconds longer. This was a clever thing I noticed when watching the movie. I actually reversed it and watched it again. Most of the X-Men movies do the same thing. The “X” stays on screen longer than rest of the logo.
Here's the X-Men logo with the “X” fade and the X-Men theme added to the studio logo. I love this variant the best.
