Getting Random movie title

I am trying to randomize the movie titles from an movie API and I keep getting the first letter of the title instead of the actual movie title

 function renderMovie(jsonObject) {
   let arrayTitle = jsonObject.movie_results;

    arrayTitle.forEach((title) => {
     let movieGenre = document.getElementById("movie-description");
     let newTitleArr = Object.values(title)[0];
     let random = newTitleArr[Math.floor(Math.random() * 
     newTitleArr.length)];

     movieGenre.innerHTML += random;
   });
 }
