Sebelum menjelaskan, penting untuk memastikan bahwa tidak ada film berjudul Eternity yang rilis pada 2010 dengan subtlemen Indonesia. Namun, film Indonesia berjudul Eternity ( Berjanji di Eternity ) yang dirilis pada 2021 memang menjadi sorotan. Ini mungkin terjadi kesalahan keterangannya waktu atau pengacauan judul. Film ini adalah produksi lokal Indonesia yang memadukan nuansa romansa dan misteri.

Wait, there's no such thing as "Eternity" directed by Chris Columbus in 2010. Wait, maybe the user is confusing the title. The correct film from that director in 2010 is "Harry Potter and the Deathly Hallows." Is there a possibility of a mix-up here? Alternatively, maybe there's an Indonesian film called "Eternity." But the user mentions "2021 subtitle Indonesia," so it's possible it's a 2021 Indonesian production. Let me verify.

I should consider the user's possible intent. They might be looking for a detailed analysis of the film and its localization for an Indonesian audience. So, I need to connect the film's themes with Indonesian culture or the 2021 subtitling context. Also, maybe there were specific events in 2021 that made the subtitling relevant, like a re-release or a festival. I should check if Eternity was re-released in 2021 or if there's something particular about the subtitle version then.
