Warning: boring post about Serenity.
Skip it. Really.
Universal got 45% of the domestic gross of Serenity - about $11.5m. Internationally, UIP released it, who (and this bit isn't an official figure, but I gather it's the case) take about another 10% (so 55% total). So, internationally, $7.33m.
In total, that's $18.83m, from a production budget of $40m. The production budget obviously has domestic and international marketing costs on top, along with distribution (which will be around $7m). Looking at around $57m.
So, all in all, at the box office Serenity took about a third of it's overall budget.
Now, there's DVD sales on top of that, however the DVD also had marketing and production costs.
An average movie makes about 60% of it's overall money -- apparently (that's a commonly quoted figure) -- from DVD sales.
Tamara is spot on about DVD sales, licensing (games, books, TV airings etc) -- once it's totalled on, it'll break even in the next few years.
The thing is, the reason Garfield is getting a sequel is this -- it make a shit load of money. Probably $400m+ profit for the studio (with DVD sales, Garfield toy licensing etc). Does anybody know anybody who liked it? I don't. Did people see it? Yep. 'cause, you know, it's Garfield.
Serenity isn't a total bomb for Universal, it got good reviews and such, and you know - no overall money loss. It could have done much worse.
