This is a speaking activity in Spanish. In this type of activity, it is important to write first what you want to say and then try to incorporate the vocabulary that is related to what you are going to talk about, so you feel more comfortable about the subject in discussion.
In this case, you have to talk about your favorite movie. This is an example of what you could say, following the questions you are given as a guide:
Mi película favorita se llama Harry Potter y la piedra filosofal. Es una película de fantasía que presenta un mundo donde existe la magia, y Harry Potter es un niño que comienza su primer año en la escuela de magia. El actor principal de la película es Daniel Radcliffe, interpreta a Harry Potter.
Me gusta esta película porque nos muestra una realidad diferente a la nuestra, y porque las aventuras de los tres amigos en el colegio de magia son muy divertidas de ver.
It is important to know as many details as you can about the film you are going to speak about, so you can answer all the question your teacher could ask you and give a very complete oral evaluation.
