Arnold Schwarzenegger vehicle “Terminator Genisys” and Channing Tatum starrer “Magic Mike XXL” are set to go toe-to-toe this weekend, with both new movies expected to hit at least $40 million at the five-day holiday weekend box office, according to early forecasts on Wednesday.

First estimates showed both films finishing their opening days Wednesday in the $9.5 million to $10 million range. The Wednesday estimates included Tuesday-night preview showings, with “Magic Mike XXL” taking in $2.4 million, edging out “Terminator Genisys” with $2.3 million at 2,527 locations.

The top end of five-day forecasts for Paramount-Skydance’s “Terminator Genisys” has been $55 million at 3,600 locations, while Warner Bros.’ “Magic Mike XXL” is predicted to finish in the mid-to-high 40s at 3,355 sites, with one tracker suggesting “Mike” would finish under $40 million.

Besides Tatum, the R-rated “Magic Mike XXL” stars Joe Manganiello, Matt Bomer, Kevin Nash and Andie MacDowell. The story centers on a road trip to Myrtle Beach, S.C., site of a stripper convention.

The original “Magic Mike” was a surprise success, opening with $39 million on its first weekend on its way to a $113 million total in the U.S. The sequel has a 59% “fresh” rating on Rotten Tomatoes, compared with 26% for “Terminator Genisys.”

The fourth frame of Universal’s “Jurassic World” and the third weekend of Disney’s “Inside Out” will also present a challenge. Both pictures could pull in numbers similar to those of the two new wide releases, racking up as much as $50 million over five days.

“Jurassic World” surpassed the $500 million domestic mark on Sunday and added $14 million in the next two days. “Inside Out” crossed $200 million on Tuesday.

“Terminator Genisys” carries a hefty $155 million pricetag for Paramount Pictures and Skydance Prods. Jai Courtney, Jason Clarke and Emilia Clarke also star in a story set in the year 2029 amid a war against machines and a fractured timeline due to time travel.

The film represents something of a test as to whether Schwarzenegger still has significant star power in the wake of poor performances by “Escape Plan” (2013) and “Sabotage” (2014).
