Answer:
Yo veré Divergente a las 7:05 en el (Cine Imax) mientras como dulces.
Step-by-step explanation:
Since we are asked for a future tense sentence in the first person, the sentence must start with "Yo veré" (I will watch). That's the subject and verb, now we add direct objects (the movie we are watching), and conditionals (where and what will you eat while watching).
The direct object is the title. Titles can be kept in their original language is most cases, but since Divergent actually was translated into Spanish and published, you can use the Spanish title "Divergente".
As for where, since you did not specify in which theater the movie is playing I just added a random one. "Cine" is the Spanish word for movie theater so you could add it to any theater name and that would be the name.
And finally, I translated candy into "dulces". Although "caramelos" might be another possible translation, it refers to a specific type of candy, whereas "dulces" is a wider category.
