We very often see the pattern - "be made ~ing" such in "The movie was made using a lot of special effects.".
Which will be the correct analysis for this pattern in the followings?;
1) The movie was made when using a lot of special effects. (a kind of adverbial clause with the conjunction - 'when' left out)
2) The movie was made of using a lot of special effects. (the preposition 'of' has been left out, which shows the construction material)
3) The movie was made by means of using a lot of special effects. (the phrase - 'by means of' has been left out)
Would hope to hear your valuable comments, while I'm inclined to above 2).
