cin only reads input up to a space or newline (enter/carriage return). When you enter in a movie title with a space, the first word gets stored in name, and the rest is passed on to the next cin. But since the next variable to be streamed into is an int, the cin fails, resulting in your error.
To include spaces, use
But this comes with a downside, too. Since you have cin's beforehand, there is a likely chance that there is a newline character hanging in the buffer which getline will catch. You can use [code]cin.ignore()[code] to catch these newlines before the getline instruction is reached. So, be careful that you clean up the buffer before calling getline.

how about this?

Instead of
But be careful of any newline character '\n' remaining in the input buffer after a previous cin >> operation. You may want to get rid of it if necessary using
cin>>name; try getline(cin, name);But be careful of any newline character '\n' remaining in the input buffer after a previous cin >> operation. You may want to get rid of it if necessary using
cin.ignore();
