Marvel Studios has recently released two teaser clips for the movie "Fantastic Four: First Steps" in just two days, and let me tell you guys, there are not much new things in it because these two trailers carry most of the scenes which we have watched already in long (2 minutes) trailer which was released by Marvel 3 months ago, and in the Final Trailer released 3 weeks ago.
Dreamer Teaser:-
In this teaser, we see the similar clip of the Fantastic Four team leaving the earth with their spaceship, and the narrator tells "Four years ago, we were dreamers", then the clips continues showing of people who are happy to see their Heroes who are trying their beast to protect the world. And the narrator continues telling "Today, we face a danger that has threatened our home" and this line might directly connects to the scene where Galactus said to "Reed Richards" "Give us your child, and I will spare the earth", and Reed Richards explained this offer in press conference too, but "Sue Storm" the mother of child (Franklin Richards) said "I am not giving him up", showing her love to her child while the whole world is in danger. Later she continues to say "We will face this together as a family", she said this because the enemies are not just behind their world, but actually want their child too. And at the last Reed Richards directly says to it's people that "We will protect you" he says this to show the people that he and his team still wants to protect their world and their people while their family is in danger especially their baby.
Incredibles Teaser:-
In this teaser, they have shown some entertaining scenes of Fantastic Four Team in the movie, and we can see some part of Heroes daily routine too, unless when a huge problem occurs. We can even see some action scenes and different abilities of our Heroes which most of the audience knows already. We even see that Fantastic Four Team always take care of themselves and their family members too, no matter of what they are facing currently and they are always ready to do something to face new problems that occurs in future as we saw it on different Trailers.
Conclusion:-
Not just these two teaser in fact many teasers from past few days are just breakdown of long Trailers, Marvel has broke these trailers into small scenes to give importance on every parts of it not just by themselves but by audience too. Most of these Teasers always show importance to child (Franklin Richards), His entire family, Galactus and his offer to Reed Richards, showing us the importance of the child, the true plans of Galactus, and showing many references related to "Dr. Doom" in "Avengers Doomsday" and "Avengers Secret Wars" with the help of actual "storyline" and "comic version" of this movie.
