You are passing no second param to the partial view so it is using the same Model as the parent view.  Your parent view's model is a List of movies so your partial view is given a List of movies, but your partial view's @model directive says it wants a single movie.  This code;

<div id="divPartialView">
    @Html.Partial("PartialMovie")
</div> 

What are you expecting the partialmovie to show?  The first movie you have in the model?  The last one?  A random one?  Every one?  If you want to list every movie with a partial view showing each then you probably want code like this

<div id="divPartialView">
    @foreach(Movie m in Model)
    {
        @Html.Partial("PartialMovie", m)
    }
</div> 

The above passes a single movie into the partial view, one at a time
