对象对象打印(Javascript)

我在我的网站上有几个按钮，它们是onclicks和js文件看起来像这样(例如一小部分):

var bestMovie = function () {
        document.getElementById("bestefilm").innerHTML = "The Fault In Our Stats | Budget: $12 miljoen - Opgeleverd: $65.3 miljoen";
    };
var buttonClick7 = document.querySelector(".bestefilm");
    buttonClick7.addEventListener("click", bestMovie);

和我的HTML是这样的:

  <input type="button" class="bestefilm" value="Welke film heeft het meest opgeleverd in juni 2014?" />
  <p id="bestefilm"></p>

它工作得很好，但我也添加了一个数组的对象，我的js看起来像这样:

var top5Movies = function() {
    var movies = new Array(5);
    movies[0] = {title: "300: Rise Of An Empire", iMDBscore: "6.6", number: "#1"};
    movies[1] = {title: "Street Fighter: Assassin's Fist", iMDBscore: "8.2", number: "#2"};
    movies[2] = {title: "X-Men: Days of Future Past", iMDBscore: "8.5", number: "#3"};
    movies[3] = {title: "The Grand Budapest Hotel", iMDBscore: "8.3", number: "#4"};
    movies[4] = {title: "Non-stop", iMDBscore: "7.2", number: "#5"};
    var geefAntwoord = movies[Math.round((movies.length - 1) * Math.random())];
    var genereerRandom = document.getElementById("random1");
    genereerRandom.innerHTML = geefAntwoord;
}
var buttonClick8 = document.querySelector(".random1")
buttonClick8.addEventListener("click", top5Movies);

和我的HTML如下:

  <input type="button" class="random1" value="Willekeurige selectie van 5 films die het meest zijn gedownload in juni 2014" />
  <p id="random1"></p>

问题是，当我按下按钮时，我会选择…，意思是"随机选择"，我得到的答案是:[object object].

我怎么能解决这个问题?谢谢。
