In this week's edition of the Variety Movie Commercial Tracker, powered by iSpot.tv, "Into the Storm" leads in spending with an estimated outlay of $9.4 million for spots that have aired 1,208 times across 42 networks through August 4. That's up from $8 million, and third place, in our previous chart. The ad-placement strategy remains the same, with Comedy Central scoring more "Storm" commercial placements than any other network for a second week in a row (SyFy was again right behind it).

Though "Teenage Mutant Ninja Turtles" ads began airing on national TV on March 28, a big surge to $8.9 million in estimated spending lands it in second place (it didn't place in our top 5 at all last time). With an estimated life-of-campaign outlay of $21.9 million so far, that means 40% of the spend over the past three months happened in just the past seven days. "TMNT" commercials were actually the most ubiquitous in our top 5 over the past week, with 1,686 airings; Nick scored the most placements among all networks.

Meanwhile, "Lucy" and "A Most Wanted Man" get knocked out of our chart, making room for "If I Stay," with an estimated $7.6 million spend, and "The Expendables 3," at $5.2 million.
