You can use some jQuery magic to do this:

$(function() {
    $('#ddlSelectCinema').prop('disabled',true);
    $('#ddlSelectSession').prop('disabled',true);
});

This code will disable the "Select Cinema" and "Select Session" drop downs. Then you need an event handler on the drop downs:

$(function() {
    $('#ddlSelectMovie').change(function() {
        $('#ddlSelectCinema').prop('disabled', false);
    });
    $('#ddlSelectCinema').change(function() {
        $('#ddlSelectSession').prop('disabled', false);
    });
});

This will not hide it, but it will disable them. You might want to also add a CSS class called 'disabled' or something and apply and remove that class as you disable/enable the. This way you can style the drop downs and make them look disabled.
