Ways to create suspence - Alfred Hitchcock

I was looking at different ways to create suspense so that I could include them in my opening to a thriller film. I need to create tension in a short time, with leaving the opening catchy so that the audience will want to watch the rest of the film and not giving too much away in the opening scene. I looked at 'The master of suspense' Alfred Hitchcock's productions of his films.

Alfred Hitchcock used suspsense over surprise in the making of his films, as he beleived that it created a new audience (during the time that he produced his films). He made his films with the use of showing or telling the audience things in which the characters are not aware of yet. This automatically builds tension as the viewers are then unaware of how the character is going to react when they finally know the truth.

Hitchcock uses repetitive props or methods in his films to create a connection to all of his work. For example, the uses of trains are in a couple of his films like 'The 39 Steps' and 'North by NorthWest'. Or the repetition of the main woman character being blonde. In one case, he made the main character die her hair so that she could be blonde.

With all the repetitions and the different ways of building suspense, he has earned his name of 'The master or suspense.' I think that, if it would be possible, to create as many as the techniques that Hitchcock has. This would make the opening to the thriller more intresting and grasping as it holds onto the audience.
