A “blockbuster”, when used talking about a film indicates that the movie has brought in a huge audience. You can use this to describe a highly successful movie.
A more personally expressive statement could be “its one in a billion”; suggesting there is one in every billion like it, so it belongs to a small group. This expression is almost always used in a positive way.
「blockbuster」は、映画について使うと、すごく大勢の観客を動員したことを表します。
大成功した映画のことです。
もっと個人的な感想を言う表現として「It's one in a billion」。10億の中に一つしかない、すごく小さなグループに入るということで、ほとんどの場合良い意味で使われます。
In the first statement, the phrase 'by far' means 'by a large amount or 'by a lot'. In the second statement, 'of all time' has been used. What this phrase means 'that has ever lived or existed'. In this case, the movie is being referred to as the biggest hit that has ever existed or that has ever been made.
So, you may say:
The movie was by far the biggest blockbuster.
or
The movie was the biggest hit of all time.
最初の例文では、"by far"（とても）という単語を使いましたが、"by a large amount" "by a lot"のように「たくさんの」「とても大きな」という意訳になります。
2番目の例文には、"of all time"（史上～）とありますが、「今までの中で～」「空前絶後の」という意味です。
この場合ですと、「映画」が空前絶後の大ヒットという事を表します。
The movie was by far the biggest blockbuster.
（この映画はとても大きなヒット作品となった。）
or
The movie was the biggest hit of all time.（この映画は空前絶後の大ヒットです。）
>That movie was the bomb.
*This sentence explains that the movie was the best and was a great hit.
.....................
>Greatest movie of all time.
*This sentence explains that this was best movie so far in history.
,.,.,.,.,....,.,..,.,.,.,.,.,.,.,.,.,,.
That movie was the bomb.
非常に素晴らしい映画でヒットしたということを意味する表現です。
Greatest movie of all time.
歴史的にもっとも素晴らしい映画であることを意味する表現です。
The movie was such a blockbuster hit I can't imagine how they could make a sequel.
Although the movie was a hit I can't see them making a sequel.
The two sentences above are great ways to express that you think a big hit movie will not have a sequel. In the first sentence you will see the word blockbuster. We use this word to describe a film that has a lot of success. You will also see the word sequel, which is a movie that continues the story of the previous movie.
